Streszczenie:
Formability of two magnesium alloys, namely, AZ80 and ZE10, has been investigated. Both alloys were supplied with a thickness of 0.8 mm. The grain structure of the as-received AZ80 alloy showed dislocations, twins and second-phase particles and-/or precipitates distributed uniformly within grains. These were not obvious on the ZE10 alloy. The investigations were carried out at room temperature for both alloys in the as-received and heat treated conditions (410oC for 1 hour followed by water quench). The heat treatment significantly changed the grain structure of the AZ80 alloy, but did not affect the ZE10 alloy apart from grain enlargement. The formability was studied on the basis of plastic strain ratio (r) and strain hardening coefficient (n) by means of tensile testing. In the as-received condition, the ZE10 alloy had a slightly better formability () than AZ80 alloy. Following heat treatment, however, the formability of the AZ80 alloy was improved significantly (by about 26%), while the ZE10 alloy did not show any significant change.

Streszczenie:
The corrosion behavior of hydrostatic extruded tube AZ80 magnesium alloy was investigated by polarization curves and electrochemical impedance spectroscopy (EIS) in simulated atmosphere. The results indicated that, the corrosion resistance of the hydrostatic extruded AZ80 magnesium alloy with uneven deformed grains and increased sub-grains were obviously weakened, with larger corrosion current density in the polarization curves and lower corrosion resistances in the electrochemical impedance spectroscopy plots. This was mainly because of the hydrostatic extrusion which made AZ80 magnesium alloy within large numbers of dislocation tangles. So the residual stress increased the electrochemical activity of magnesium alloy which reduced the corrosion resistance of magnesium alloys.

The atmospheric corrosion behaviors of AZ80 magnesium alloy are investigated by exposure test in different testing sites. After four months exposure test, the corrosion morphologies and the component of the corrosion products were observed by the scanning electron microscopy (SEM) equipped with energy-dispersive analysis of X-ray (EDAX). The corrosion rates of AZ80 magnesium alloys were calculated by mass-loss. The results indicated that the corrosion resistance of AZ80 magnesium alloy in the sea environment is the worst. The corrosion degree of the back surface is worse than the front side. The corrosion products are mainly formed by carbonate, and contain small amount of chloride in most environments, while in Xishuangbanna and Jiangjin area contain a little sulfate.

Thermomechanical treatment was adopted to improve the comprehensive performance of AZ80 magnesium alloys in this paper. The influence of varying the thermal processing parameters and deformation on the microstructure and mechanical properties of AZ80 magnesium alloy was studied, and the optimal process of themomechanical treatment was obtained. The experimental results show that the hardness increased with the increasing of deformation and the hardness is up to the peak value with 30% deformation. After aging, the hardness measurements and microstructure analysis results show that the hardness increased with increasing aging temperature, and reached the peak value at temperature 170°C, while the hardness decreased sharply when the temperature goes beyond 170°C. After thermomechanical treatment, the grains of AZ80 magnesium alloy became uniform and fine. The roles of both deformation strengthening and dispersion strengthening were to improve the mechanical property of AZ80 magnesium alloy.

AZ80 magnesium alloy was semi-continuously cast under different physical fields which were conventional direct chill (DC) casting, low frequency electromagnetic casting (LFEC), ultrasonic casting (USC) and electromagnetic-ultrasonic combined casting (ECUC), respectively. The effect of different physical fields on solidification structures of AZ80 alloys was investigated. The results show that compared with the conventional DC casting, structures of AZ80 alloys billets cast with LFEC and USC have been greatly refined. The effective refinement takes place in the edge of billets when LFEC is applied. However, the effective refinement takes place in the center of billets when USC is applied. When combination of low frequency electromagnetic and ultrasonic fields is applied during semi-continuous casting AZ80 magnesium alloy billet, structures of AZ80 alloys are refined significantly in the whole billets everywhere and more uniform.

Aluminum (Al) coating was thermally sprayed on the surface of AZ80 magnesium (Mg) alloy. The Al-coating was deformed at 400°C with different deformation degrees of 15%, 30%, 45%, 60% and 80%. The corrosion properties of the AZ80 Mg alloys coated with Al-coatings were studied by potentiodynamic and galvanic tests in 3.5% NaCl solution; the adhesion strengths between Al-coatings and AZ80 substrate were also measured simultaneously by tensile test. The results showed that, Al-coating could decrease the corrosion rate of AZ80 Mg alloys, and the corrosion rate was related not only with the density of Al-coating but also with the adhesion strength of Al-coating. Before the formation of dense Al-coating, the corrosion rate of Al-coated AZ80 Mg alloys decreased with the increasing of bonding strength of Al-coating; after the formation of dense Al-coating, the corrosion rate of Al-coated AZ80 Mg was mainly determined by the structure of Al-coating. It was also revealed that with the increasing of deformation degree, the corrosion rate of the Al-coated AZ80 Mg alloys first decreased then increased, while the adhesion strength increased gradually. The corrosion rate of AZ80 Mg alloy coated with 60% deformed Al-coating was the lowest, which was only 19% of that of the AZ80 substrate.

In this study, the comprehensive performance of AZ80 magnesium alloy was improved by solution treatment and multi-step ageing treatment. The effects of different thermal processing parameters on the microstructure and mechanical properties of AZ80 magnesium alloy were studied. The experimental results show that the optimal process of solution treatment for AZ80 alloy is heated at 420°C for 5h, which the β phase dissolve thoroughly into the α substrate. After first-stage ageing treatment, the hardness of samples varied as the ageing temperature, and had higher hardeness at temprature 180°C. While in the second-stage ageing treatment, the sample got the ageing peak value at 210°C for 10h. After two-stage treatment, the grains of AZ80 magnesium alloy became homogeneous and fine, and the second phase distributes along the grain boundary and plays an important role of dispersion strengthening. Above all, the optimal heat treatment process of AZ80 magnesium is solution treated at 420°C for 5h, as well as ageing at 180°C, 4h and 210°C, 10h.

The results indicated that AZ80 magnesium alloy shows dynamical recrystallization when hot compessed, the recrystallization is prone to happen and the stress peak decreases with the temperature increased, and the critical strain to produce the transformation of recrystallization augments with the strain rate increased.

Streszczenie:
The multiaxial deformation of magnesium alloys is important for developing reliable, robust models for both the forming of components and also analysis of in service performance of structures, for example, in the case of crash worthiness. This work presents a combination of unique biaxial experimental tests and biaxial crystal plasticity simulations using a visco-plastic self-consistent (VPSC) formulation conducted on AZ80 magnesium alloy in two different conditions - extruded and a more weakly textured as cast condition. The experiments were conducted on tubular samples which are loaded in axial tension or compression along the tube and with internal pressure to generate hoop stresses orthogonal to the axial direction. The results were analyzed in stress and strain space and also in terms of the evolution of crystallographic texture. In general, it was found that the VPSC simulations matched well with the experiments, particularly for the more weakly textured cast material. However, some differences were observed for cases where basal < a > slip and {10¯12} extension twinning were in close competition such as in the biaxial tension quadrant of the plastic potential. The evolution of texture measured experimentally and predicted from the VPSC simulations was qualitatively in good agreement. Finally, experiments and VPSC simulations were conducted in which samples of the extruded AZ80 material were subjected to a small uniaxial strain prior to biaxial loading in order to further explore the competition between basal slip and extension twinning.

In this study the evolution of microstructure and the mechanical properties of an AZ80 magnesium alloy were investigated. It examined prepared samples of AZ80 magnesium alloy before and after processing by severe plastic deformation (SPD) using the High-Pressure Torsion (HPT) technique. An AZ80 magnesium alloy with a chemical composition of Mg-8.7% Al-0.5% Zn was processed using HPT. The processing was conducted at room temperature, 296 K, and at the elevated temperature of 473 K under quasi-constrained conditions, using an imposed pressure of 6.0 GPa at a speed of one revolution per minute (rpm) through different numbers of turns: 1/4, 1, 3, 5 and 10. Processing magnesium alloy by HPT produced excellent grain refinement in the alloy, and it prevented the samples from developing cracks and segmentation at ambient temperature better than the other popular technique of SPD, for instance Equal-Channel Angular Pressing (ECAP). The initial microstructure and the microstructural development after HPT processing were subsequently examined by optical microscopy (OM), scanning electron microscopy (SEM) and Transmission Electron microscopy (TEM). Microstructural investigations for the as-received condition showed an average grain size of ~25 m. Optical microscopy images revealed microstructural evolution at both room and elevated temperature after the HPT process. The small proportion of refined grains at the edges expanded towards the disc centre with consecutive increasing numbers of revolutions. The TEM images demonstrate an evolution toward homogeneity at increasing numbers of revolutions. The final average grain size after 10 turns when the alloy was processed at room temperature was ~200 nm and ~330 nm when the alloy was processed by HPT at 473 K. The selected area electron diffraction (SAED) images of HPT samples after 10 revolutions show a fully developed ring at room temperature, indicating a microstructure with high angles of misorientation grain boundaries, and a less developed ring at 473 K. Microstructural observation through the disc thickness demonstrates more heterogeneity in the vertical than the radial direction. Vickers microhardness (Hv) values were taken along the disc diameter (radial direction) and over the total surface of the discs (colour-coded contour mapping). The results of Vickers microhardness (Hv) measurements along the diameters of the discs verify the heterogeneity of HPT deformation at lower numbers of turns. In the samples, the microhardness values increased rapidly at the edges of the disc, while the centres showed a lower value, and this large difference confirms the heterogeneity of HPT deformation in the early stages. With further straining samples showed a significant increase in microhardness values from the edges towards the disc centre. The microhardness values of samples processed by 5 and 10 turns showed a reasonable homogeneity across the disc diameter, with an average value of ~120 Hv when AZ80 was processed at room temperature and an average value of ~110 Hv when processed at 473 K. Likewise, three selected discs processed by HPT for 1, 3 and 10 turns at both 296 K and 473 K were sectioned vertically across their diameter to be tested by (OM) and Vickers microhardness (Hv) through their thickness (axial direction). The results of (OM) and Vickers microhardness (Hv) confirmed the high heterogeneity in the axial direction than the radial direction. Subsequent to the HPT process at room temperature, tensile specimens were cut from the processed discs and pulled in tension to failure at different tensile test temperatures (473, 523 and 573 K) and strain rates of (1.4×10-4 s-1, 1.4×10-3 s-1, 1.4×10-2 s-1 and 1.4×10-1 s-1). The superplasticity of AZ80 magnesium alloy was confirmed for the first time (to the author’s knowledge) at a maximum elongation of 645% when the alloy was pulled in tension to failure at 573 K using strain rate of 1.4×10-4 s-1. Moreover, the alloy exhibited a lower temperature superplasticity when it attained 423% at 473 K. Despite this superplasticity, AZ80 magnesium alloy does not show the predicted behaviour of increasing ductility with increased imposed strain during HPT process and decreased average grain size. The maximum elongation was reached in a sample processed by HPT for one turn, in which a smaller average grain size and the homogenous microstructure were not achieved.

Streszczenie:
The continued interest in the use of magnesium alloys for new applications demand the successful production of high quality wrought alloys. Magnesium Elektron seek to reliably produce high quality alloy billets by the DC casting method combined with ultrasonic inspection. The main objectives of this study are to characterize the defects which are currently found in the material and to understand the ability of the ultrasonic inspection technique currently employed to detect the defects. This study began by locating defects using the ultrasonic inspection method which were then characterised using X-ray Computed Tomography (XCT) 3D imaging technique. Attempts were then made to understand and simulate the mechanisms by which the defects form during the casting process. The simulations were used to investigate the flow patterns during casting and the growth kinetics of the intermetallic phase. The initial phase of this research established that the defects found comprised of an entrained oxide film entangled with an abundance of intermetallic phase particles. These defects were found to be present in the size range of 0.5 – 5 mm, and were deleterious to the materials mechanical properties. Greater understanding of the ultrasonic inspection process was achieved and informed improvements to assisting the production of high quality feedstock. Simulation of the formation of the defects indicated that there was a region in which the oxide films could form and be free to enter into the final cast product. Simulation of the growth of the intermetallic particles demonstrated that precipitation from the liquid occurs in the mould during which particles are carried by the melt flow and experiences a complex thermal history. The combination of the two phases was established to be due to entanglement of the oxide and particles which when combined will settle out of the melt as a single defect. Improved filtering and melt handling methods were recommended to eliminate the defects and reliably produce high quality alloys.

The study mainly investigates into the formability of AZ80 magnesium alloy tube and bar under hot extrusion. The contents of investigation are divided into two parts. The first part is the extrusion of tube. By using Taguchi’s experimental planning method, the study undergoes the construction and analysis of extrusion experiment. The process parameters considered in the study include the heating temperature of materials,initial extrusion speed, heating temperature of ingot container and lubricant. The study also uses Taguchi orthogonal array to make the experimental plan. After the experiment is done, the extruded finished products are brought to receive a test of mechanical properties. The data of mechanical properties acquired in the test are further analyzed by Taguchi method. The study investigates how the extent of influence of different process parameters on extrusion and fabrication is correlated with the mechanical properties of finished products. The second part uses trial and error method to plan the experiment of AZ80 magnesium alloy bar. The extruded finished products have to receive a test of mechanical properties. Then all the data of mechanical properties acquired in the test are analyzed. These results are compared with the results of extruded tube. Finally, it is hoped that the conclusions made by the study can be provided as a reference for the industry of magnesium alloy processing.

This study mainly focuses on precipitation hardening behavior and superplasticity of AZ80 magnesium alloy. The precipitation hardening experiment was conducted between 125-300℃. The influence of the precipitate on mechanical properties was measured by microhardness test and tensile test. The precipitate was investigated in detail by XRD, OM, SEM and TEM. The superplastic experiment focuses on three different rolling directions. The temperature ranges from 200-400℃ and the strain rates were 3×10-3、1×10-3 and 3×10-4(s-1). The results were analyzed by OM and SEM to further understand the influence of temperature and strain rate on microstructural evolution. The result of the precipitation hardening experiment indicates that each aging temperature between 150-300℃ shows hardening effect. The highest hardness is occurred at 175℃/256 h and the hardness increment is about 38%. The result shows that the hardness increment is low compared with precipitation-hardenable aluminum alloys. This is influenced by the nature of Mg17Al12 precipitates. The precipitates can be divided into continuous and discontinuous precipitates by their forming mechanism. They can be further divided into lamellar, elliptical, intergranular, Widmanstätten structure and irregular slab by their morphologies. Because the precipitate can not effectively resist dislocation moves, the hardening effect is poor. At different aging temperature the morphology, the size, and the distribution density of Mg17Al12 precipitates are also different. These reasons then lead to different hardness. The result of superplastic experiment shows that the material has best elongation (about 350%) at 300℃/3×10-4s-1. The rapid elongation increase at this temperature has two reasons: one is because 300℃ is close to the recrystallization temperature of the material, dynamic recrystallization then occurs and provides enough grains for grain boundary sliding which produces large deformation; the other reason is because Mg17Al12 precipitates rapidly at 300℃ and most of them are formed on grain boundaries, they can effectively impede grain growth to remain the fine grain structure. These two effects appear at the same time and contribute to high elongation.

Magnesium alloys are considered as potential candidates for numerous applications, especially in transportation vehicles or lightweight sectors for 3C products owing to their excellent properties, such as low density, high specific strength, high damping capacity and high recycle ability. The AZ series is mainly based on the Mg-Al alloy system and leads most of the magnesium alloys. If the Al addition in these AZ-series magnesium alloys exceeds 6 mass%, the β-Mg17Al12 inter-metallic compounds will precipitate within the matrix and the mechanical strength increases. Furthermore, adding slight Zn into Mg alloys is to enhance their corrosion resistance. These Zn atoms may also have the effect of solid-solution strengthening. However, it is commonly recognized that magnesium possesses poor formability because of its hexagonal close-packed structure. Adding Lithium with extremely low density 0.534 g/cm3 can improve this shortcoming and further reduce weight. In the present study, by 3mass% addition of Lithium on AZ80 Mg alloy, we study mechanical properties of as-extruded magnesium alloy. Furthermore, to more understand this AZ80+3mass% Mg alloy, the effects of heat treatments (T5 and T6) on its precipitation behavior and mechanical properties will be systematically investigated. Experimental results show that adding 3mass% Li to AZ80 alloy can obviously increase the ductility. Meanwhile, as-extruded AZ80+3%Li specimens will produce the Mg17Al12+AlLi precipitates after aging from 110℃ to 230℃. The 110℃ aged specimen has a maximum tensile strength of 356 MPa with corresponding aging time of 16 hours. The 450℃ solution-treated specimens will produce the AlLi precipitates after aging from 110℃ to 230℃. The 110℃ aged specimen has a maximum tensile strength of 373 MPa with corresponding aging time of 32 hours. However, the addition of 3mass% Lithium on AZ80 Magnesium alloy will reduce the corrosion resistance due to the highly activity of Lithium and hydrolitic reaction of AlLi precipitate.
