Abstract:
Abstract The paper presents the determination of the velocity of the vapor front along the outer wall of a cylindrical specimen in the process of two-dimensional axisymmetric quenching of the samples in thermal oils. One thermal oil is Isorapid 277 HM heated to 40°C and the other thermal oil is Marquench 722 heated to 90°C. The experimental setup of the work consists of heating to a temperature of 850°C, then quenching three dimensionally different cylindrical probes. The dimensions of the probe were: ϕ25x100 ϕ50x150 and ϕ75x225 mm. All quenchings were done in strictly controlled conditions of the flow rate of the quenchant around the cylinder as well as maintaining the temperature of the quenchant within the maximum 40±2.5°C or 90d3°C, during the quenching of the samples. The velocity of movement of the steam front on the outer surface of the cylinder was determined from the time-measured values of temperatures at the marked points of each sample. The analysis of the steam front movement velocity along the cylinder wall starts from the moment the lower base of the probe touches the quenchant. During the process of immersing the test probe in the quenchant, in addition to measuring the temperatures in time, the time of lowering the probe to contact with the quenchant sample was also measured. The approximate average velocity of the vapor front was determined based on the indications of the lower and middle thermocouples located 1.5 mm below the outer surface of the cylinder wall. Based on the distance of one half the height of each probe and time, the velocity of the steam film movement or the kinematics of the steam film wetting was obtained. The obtained results were compared with the results of quenching in water and aqueous solutions of the same probes under the same strictly controlled conditions.

Abstract:
There are many literature references comparing the use of aqueous polymer quenching solutions with petroleum oil quenchants for a wide range of steels of varying hardenability and the relating parameters of describing properties of the quenching mediums. There are relatively little similar relating correlations between parameters of describing properties of the different quenching mediums. The quenchants used included: conventional quenching oil, martempering oil, and 5% and 25% aqueous polymer quenchant solutions (APQSs) of a polymer quenchant. These quenching media were selected to represent a broad range of quench severities as quantified by cooling curve analysis (ASTM D 6482) using a standard Inconel 600 probe and the Tensi Agitation Device. The test of correlation conducted between the Hardening Power parameters according to examples of oils and polymers. The enable work results in applying the Hardening Power independently from equation calculated for different quenching mediums and their work parameters.

Abstract:
In recent decades, due to the increase in computing power, mathematical modelling has experienced a fulminant development in almost all areas. The aluminium industry is one of these areas. One of the main processes for improving the properties of certain aluminium alloys is the solution heat treatment and quenching process. The most common quenchant used for aluminium alloys is water. The main advantage of using a water quenchant is that water can provide the rapid quenching. By considering the temperature dependence of the thermo-physical properties, the non-linear thermo-mechanical direct coupled analysis of the quenching process for a 6061 aluminium alloy plate was achieved. The structural stress due to solid thermal effects were studied by using ANSYS finite element software. The quenching rate, which determines the plate deformation after quenching, was estimated and validated on independent equipment for the research of aluminium alloy quenching process. The developed mathematical model serves as a tool by simulation of various scenarios that may occur in the industrial process.

Abstract:
The control of quenching process has been investigated in this study by developing a quench system design to simulate the quenching process and measure the time – temperature history inside the sample during the cooling stage. The main purpose of this quench system is to evaluate the quench power of different quenchant at different conditions (type, temperature and agitation).A stainless steel sample was used with a suitable measurement as a probe in designing this quench system.The performance of two of quenchants (water and brine) with different conditions was investigated, and the designed probe was used to illustrate the effect of quenching parameters (quenchant type, temperature and its agitation) on cooling curves and cooling rate.The quenching system has proven its ability to work effectively and the results showed that heat transfer properties were significantly affected by quenchant parameters.

Abstract:
In the paper the results of testing three types of FUCHS oils: Thermisol QH 120, Thermisol QH 10 and Thermisol QB 46 are discussed. The main attention is paid to critical heat flux densities evaluation because they create a basis for optimizing cooling intensity of any liquid quenchant. In the paper is underlined that any film boiling during quenching is undesirable since it is a reason for big distortion and non-uniform surface harness. It is shown that intensive quenching decreases distortion of steel parts during quenching. To eliminate film boiling during quenching in mineral oils, optimal temperature of oil should be chosen which maximize the first critical heat flux density and special additives should be used to decrease initial heat flux by creating surface micro-coating. Along with the evaluation of heat transfer coefficients, critical heat flux densities inherent to liquid quenchant must be measured first to optimize quenching processes. International DATABASE on cooling characteristics of liquid quenchants must include critical heat flux densities, initial heat flux densities, and heat transfer coefficients allowing optimizing and governing quenching processes.

Abstract:
ABSTRACT We use the simba cosmological galaxy formation simulation to investigate the relationship between major mergers ($\lesssim$4:1), starbursts, and galaxy quenching. Mergers are identified via sudden jumps in stellar mass M* well above that expected from in situ star formation, while quenching is defined as going from specific star formation rate (sSFR) $\gt t_{\rm H}^{-1}$ to $\lt 0.2t_{\rm H}^{-1}$, where tH is the Hubble time. At z ≈ 0–3, mergers show ∼2–3× higher SFR than a mass-matched sample of star-forming galaxies, but globally represent $\lesssim 1{{\ \rm per\ cent}}$ of the cosmic SF budget. At low masses, the increase in SFR in mergers is mostly attributed to an increase in the H2 content, but for $M_*\gtrsim 10^{10.5} \,\mathrm{ M}_{\odot }$ mergers also show an elevated star formation efficiency suggesting denser gas within merging galaxies. The merger rate for star-forming galaxies shows a rapid increase with redshift, ∝(1 + z)3.5, but the quenching rate evolves much more slowly, ∝(1 + z)0.9; there are insufficient mergers to explain the quenching rate at $z\lesssim 1.5$. simba first quenches galaxies at $z\gtrsim 3$, with a number density in good agreement with observations. The quenching time-scales τq are strongly bimodal, with ‘slow’ quenchings (τq ∼ 0.1tH) dominating overall, but ‘fast’ quenchings (τq ∼ 0.01tH) dominating in M* ∼ 1010–1010.5 M$\odot$ galaxies, likely induced by simba’s jet-mode black hole feedback. The delay time distribution between mergers and quenching events suggests no physical connection to either fast or slow quenching. Hence, simba predicts that major mergers induce starbursts, but are unrelated to quenching in either fast or slow mode.

Abstract:
Quenching is commonly used for improving material properties of steel tubes because of their numerous applications. However, quenching generates some residual stress and deformation in the material due to rapid temperature fluctuations. The properties of the steel are strong functions of these variable temperatures and therefore, the estimated stress and deformation by constant property or static quenching analysis are not very realistic. This study describes the first extensive study of the quenching process of a steel tube including temperature dependent properties by three liquid quenchants using the dynamic fluid–structure interaction quench model. The cooling characteristics of the three liquid quenchants are compared to each other along with the transient temperature distributions in the steel tube. The time-varying nodal, axial, and radial residual stress and deformation of the tube are studied. It is found that, the effectiveness of quenching does not depend only on a particular quenchant, but also on the temperature-varying properties of the steel and the uniformity of the cooling which ultimately determine the criteria for selecting a suitable quenchant for a specific purpose.

The excessive residual stress induced by quenching in steels will easily result in distortion and failure of parts. In order to obtain the more suitable quenchant, quenching process of Cr12MoV steel with different mediums involving water and oil are simulated, respectively. In present paper, the influence of nonlinear surface heat transfer coefficient, thermodynamic parameters and latent heat are considered comprehensively. The distribution of temperature, microstructure, hardness and residual stress after quenching for Cr12MoV steel are simulated by DEFORM finite element software. According to the results mentioned above, the variations of each field of the steel are analyzed.

Abstract:
This research proposes a method to achieve laser quenching and laser forming simultaneously. This technique uses a diode laser to produce thin steel sheet-assuming parts, such as springs and hinges. Energy and time are saved by combining the advantages of laser quenching, which has high input heat efficiency, and laser forming, which, unlike press molding, does not require metal molds. In this study, laser-quenching molding was performed for an entire thin steel plate, and the influence on warping was investigated. Furthermore, the proposed method was evaluated under repeated quenchings for different cross-sections of a workpiece. The results indicated that the technique prevented bending deformation during the next laser scan and reduced warping by increasing the second moment of area of the entire workpiece.

Abstract:
The fluorescence rise kinetics in saturating light display two well separated components with largely different properties. The rapid rise from F0 to a first intermediate level, I1 is photochemically controlled, while the following phases leading to a secondary intermediate level, I2 and to a peak level, P, are limited by thermal reactions. Treatments which primarily affect components at the photosystem II donor side are shown to increase quenching at I1 and/or to suppress the secondary fluorescence rise to I2. Preillumination by single turnover saturating flashes causes I1- quenching oscillating with period-4 in dependence of flash number. It is suggested that this quenching correlates with (S2 + S3) states of the watersplitting enzyme system. Suppression of the secondary, I1 - I2 rise component is invariably found with treatments which lower electron donation rate by the watersplitting system and are known to favor the low potential form of cyt b 559. Three different mechanisms are discussed on the basis of which donor-side dependent quench­ing could be interpreted: 1) Non-photochemical quenching by accumulation of the P 680+ radical cation. 2) Dissipative photochemical quenching at a special population of PS II centers (β- or non- B centers) displaying low donor capacity and high rates of charge recombination. 3) Dissipative photochemical quenching via cyclic electron flow around PS II, involving alternate donors to P 680+ (like cyt b 559 or carotenoid in their low potential forms), which can compete when donation rate from the water splitting system is slowed down. The possibility of donor-side limitation also being involved in “energy dependent” quenching is discussed.

Abstract:
The main objective of the present work was to investigate the opportunity for the use of light hydrocarbons as quenching agents to quench high temperature gas streams. When light hydrocarbon, for example propane, is introduced into a hot gas, for example synthesis gas, the cooling of hot gas will occur both by dilution and by endothermic reactions of hydrocarbon. Thus, the hot gas may be quenched to a lower temperature. At the same time, thermal energy present in the hot gas may be recovered in the form of desired products that are produced during hydrocarbon cracking. This type of quenching is called for chemical quenching. A proof-of-concept study would be performed, but was not completed because of problems with a realization of experimental conditions and problems with equipment.Methane pyrolysis experiments were performed at high temperatures 1400 and 1450 °C. Short residence times and high dilution with hydrogen were applied in order to minimize coke formation. Methane conversions, selectivities and yields of products for different experimental conditions were calculated from the gas chromatographic analysis. The aim of pyrolysis experiments was to validate that the experimental set-up Pyrolyserigg works properly. This was done by comparison of experimental results with results that were obtained before on the same set-up and by comparison with a literature data. After the work of Pyrolyserigg was verified, it was possible to modify existing cooling/quenching system. A new quencher part that gives opportunity to introduce a cold gas into hot gas, heated by high temperature furnace, was designed. The quencher part was designed in a way that the temperature of hot gas entering the quencher and temperature of cooled gas mixture leaving the quencher could be measured. Thus, quenching effect (temperature drop) could be measured.Three types of experiments were performed after modification of cooling system: experiments with only hot inert gas (N2), experiments with a hot nitrogen gas «quenched» by methane, and hot nitrogen gas quenched by propane. Hot gas temperature and gas flows were varying in order to study the modified system's behaviour. Experiments with a hot nitrogen showed that there is a limit for maximum obtainable temperature inside the quencher, 1195 – 795 °C, for the given quencher design. A high temperature gradients between measurements points were registered that may be an indication of high heat losses. The temperature gradient increases with increasing gas temperature and decreases with increasing gas flow.Quenching effect (temperature drop) was measured in quenching experiments with propane, and expected temperature drop was calculated for the applied experimental conditions. Low measured temperature drop in quenching experiments indicates poor mixing of hot and cold gases. Quenching effect of propane introduction increases with increasing hot gas temperature because heat consumption by endothermic reactions increases, that is a consequence of increasing propane conversion.A product mixture from quenching experiments with propane was analysed, and conversion of propane, yield and selectivities to products were calculated. Ethylene and propylene are considered to be most valuable products. Ethylene yield increases with conversion and is around 37 % at 100 % conversion. Propylene yield goes through a maximum at 55 % conversion and approaches zero at 100 % conversion. The main identified problems for the proof of concept study are a poor gas mixing, high temperature gradients through the quencher and high heat loss from the quencher part. In addition, problems with connection ceram tube – quencher at high temperature have occurred.

Abstract:
Nonlinear luminescence quenching has been documented in numerous systems such as organic crystals, rare earth insulators, laser materials, semiconductors, and phosphors. In each of these systems nonlinear luminescence quenching occurs under conditions of high excitation density from interactions between excited centers, the result is an additional nonradiative decay pathway that lowers luminescence quantum efficiency. During investigations into the spectra and dynamics of Eu2O3, an apparent saturation dip in the excitation spectra of nano-sized Eu2O3 particles was observed. This thesis describes the investigation into the nature of the saturation effect. The samples studied using luminescent spectroscopy included micron sized Eu2O3 crystals of both cubic and monoclinic phases, nanocrystal monoclinic Eu2O3, and a large fused crystal of monoclinic Eu2O3. It was determined that the saturation effect was due to nonlinear luminescence quenching occurring at the wavelengths of absorption maxima. The mechanism of nonlinear luminescence quenching was concluded to be upconversion by energy transfer.

Abstract:
Heat treatment of different steel products have existed for thousands of years. It has always been an important tool to get the microstructure and resulting properties such as hardness and case hardness and it is even more important today than ever before. This project concentrated on the quenching process and means to decrease the distortion caused by this process. The effect of different oils, temperatures, agitation and if gas quenching could give better results were investigated. The results showed that Miller´s 75 quench oil was better than Park´s 420 at slow agitation and that the viscosity of the oils influenced how much changes in agitation speed and oil temperature affected the distortion. It also shows that gas quenching is an alternative to oil quenching if the microstructure can be improved. Otherwise using Miller´s 75 with low agitation in the Surface combustion furnace will give best results.

Abstract:
GaN is a III-V semiconductor that is a promising material used in production of light emitting devices and high power/high frequency electronics. The electronic and optical properties of GaN are subdued by defects that occur during the growth processes of this material. The emitted photoluminescence (PL) from optically excited GaN gives insight into the origins and effects of point defects within the crystal lattice structure of GaN. In this study, PL spectroscopy is used to examine and analyze the point defects that occur in Zn-doped GaN. The blue luminescence band seen in undoped and Zn-doped GaN have identical fine structure and properties. This band is attributed to a ZnGa acceptor. In Zn-doped, the PL intensity quenches abruptly at certain temperatures, which increase with increasing excitation intensity. This behavior is different from the PL quenching in undoped GaN. The PL behavior was simulated with a phenomenological model based on rate equations. A program created with mathematical modeling software, in conjunction with the basic rate equations, was used to explain the unusual behavior of the abrupt thermal quenching observed in Zn-doped GaN.

Abstract:
Abstract Vegetable oils are currently using basestocks for biodegradable and renewable quenchant formulation. However, there are relatively few references relating to their true equivalence, or lack thereof, relative to the quenching performance of petroleum oil-based quenchant formulations. To obtain an overview of the variability of vegetable oil quenching performance, cooling curves were determined, and the heat transfer coefficient profiles were calculated at the Institute of Materials Modification and Modeling School of Materials Science and Engineering in Shanghai, China. The vegetable oils that were studied included canola and palm oils. Cooling curves were obtained using the Tensi multiple surface thermocouple 15 mm diameter x 45 mm cylindrical Inconel 600 probe. For comparison, similar data were obtained with Houghtoquench HKM, an accelerated petroleum oil quenchant. The results of this work will be discussed here.

Abstract:
Abstract Quench cracks became a challenge in large serial production of martensitic components. The geometry is simple, and concentrations of stresses from the geometry itself were not indicated by numerical simulation. Grain boundary ferrite is presented in the component surface from where the cracks start. An example from another application is interesting to consider; titanium grade 5. Grain boundary alpha on prior beta grain boundaries is not accepted for aerospace applications. The volume for plastic deformation in the phases along the grain boundaries is restricted. The ductile part of the fracture indicates forces from unbalanced quenching and elevated temperature at time of crack start. The general focus for improvement will be overcritical surface temperature, vapor phase break and mix of turbulent/lamellar flow. More effective quenching around the whole component is, in this case, assumed to be better than slower quenching.

Abstract:
The transient pool boiling heat transfer of zircaloy and stainless steel rodlets was investigated using a quenching method. The influences of quenchant temperature, test specimen size, and material property were examined. The groove-structured surface was also prepared and tested, which could be a valuable attempt to study the effect of a machined surface structure of a vertical rodlet on the rapid cooling heat transfer performance. A test specimen with a small volume-to-heat transfer surface area and small heat capacity showed a shorter quenching time. In the low quenchant temperature condition, a stable film boiling regime was likely to be hardly observed. The grooved surface appeared to have a shorter quenching duration, which could be due to its small volume-to-area ratio. In addition, the groove-structured portion seemed to help the liquid make contact with the heated wall earlier than the plain portion. Based on this work, it was found that the quenching duration and the position of vapor film rupture can be controlled by the surface structure.

Abstract:
Abstract The heat treatment operation which is carried out post manufacturing is optimized. Simulation of the carburizing and quenching processes with parameter optimization are combined to attain the desired surface hardness with controlled distortion of final products. Parameters of interest for optimization include, the carbon content of gas, carburizing dwell time, material temperature before quenching, quenchant temperature and the heat transfer coefficient. The response surface method is used to obtain closed-form models of the objective (surface hardness) and the two constraints (hardness variance and physical distortion) in terms of the design variables. A finite element simulation tool is used to predict the material response (volume fraction of different phases, temperature and stress/strain) during the carburizing and quenching processes. This paper summarizes the methodology that is used to optimize the carburizing and quenching processes of an axisymmetric disk.

Abstract:
The 193-nm ArF pulsed laser photolysis of HNCO, NH, and N2H4 produced NH(a1Δ). Its lifetime was measured as a function of quenching species concentration by LIF using the a1Δ → c1π transition near 325 nm. The rate coefficients for quenching were found to be 7.5 ± 0.6 × 10−14 for N2, 2.9 ± 0.6 × 10−12 for H2, 7.3 ± 1.0 × 10−13 for HF, 6.3 ± 1.0 × 10−13 for F2, 1.62 ± 0.16 × 10−11 for HNCO, 1.10 ± 0.08 × 10−10 for NH3, 1.7 ± 0.2 × 10−10 and <10−15 for He.
