Abstract:

The effect of tool traverse and rotation speeds on the microstructures and mechanical properties are quantified for welds between non-age-hardening Al5083 and age hardening Al2024 and compared to single alloy joints made from each of the two constituents. In this paper, we report the results of microstructural, mechanical property investigations of Al5186Al2024 friction stir welds produced using various rotations and traveling speeds of the tool to investigate the effects of the welding parameters on the joint strength. Metallographic studies by optical microscopy, electron probe microscopy, and the utilization of the X-ray diffraction technique have been conducted. It was found that the weld properties were dominated by the thermal input rather than the mechanical deformation by the tool. In particular the larger stresses under the weld tool on the AA5186 side compared to the AA2024 side are related to a transient reduction in yield stress due to dissolution of the hardening precipitates during welding prior to natural aging after welding.

Abstract:

The force generation, joint mechanical and metallurgical properties of friction stir corner welded non-heat treatable AA 5086 aluminum alloy are investigated in this paper. The friction stir welding process is carried out with the plate thicknesses of 6 mm and 4 mm. The welding speed, tool rotational speed and tool plunge depth were considered as the process parameters to conduct the welding experiments. The machine spindle motor current consumption and tool down force generation during friction stir welding were analyzed. The microstructures of various joint regions were observed. The tensile samples revealed the tensile strength of 197 MPa with tool rotational and welding speeds of 1,000 rev/min and 150 mm/min respectively, which is 78 % of parent material tensile strength. A maximum micro hardness of 98 HV was observed at thermomechanically joint affected zone, which was welded with tool rotation of 1,000 rev/min and welding speed of 190 mm/min.

Abstract:

Background:Patients with idiopathic inflammatory myopathies (IIM) might suffer from irreversible damage once inflammation has decreased. Autoantibodies are found in up to 80% of patients with IIM and are coupled with specific clinical features. Whether autoantibodies can be used as biomarkers to predict patterns of damage in IIM remains unknown.Objectives:To investigate the association between autoantibodies and organ damage in patients with IIM using longitudinal national register data.Methods:Data were retrieved from the electronic Swedish Rheumatology Quality Register (SRQ). Patients (n=302) with a clinical diagnosis of IIM (2017 EULAR/ACR criteria) were included. Autoantibody status was tested by either line blot or RNA- and protein immunoprecipitation; HMGCR and FHL-1 autoantibodies were tested by ELISA. Patients were grouped into six categories of autoantibodies (Table 1). TheMyositis Damage Index(MDI) score was applied to measure organ damage using both components (extentandseverity) as a continuous variable and were analyzed using generalized estimating equations (GEE). A categorical variable for each time point of MDI assessment since diagnosis was created to adjust for time (Table 2). A base model which included autoantibody group and time was fit. Other potential predictors included age at diagnosis, sex, disease duration from diagnosis to inclusion to SRQ, arthritis, Raynaud, mechanics’ hands and heart involvement at registry; core set measures at each MDI time point allowing multiple longitudinal observations were also tested.Table 1.Clinical diagnosis and autoantibody groups.DiagnosisN (%)Polymyositis119 (38)Dermatomyositis (DM)99 (33)Inclusion body myositis35 (12)Amyopathic DM9 (3)Juvenile DM8 (3)Low probability myositis32 (11)Autoantibody286 (%)Antisynthetase (AS)74 (26)Necrotizing myopathy NM)20 (7)DM- specific44 (15)FHL-118 (6)Associated antibodies AA)50 (18)Negative to any80 (28)AS: Jo1, PL7, PL12, EJ, OJ;NM: SRP, HMGCR;DM-specific: TIF1γ, Mi2, MDA5, SAE;AA: Ro52, PmScl, U1RNP, KU.Table 2.Predictors of damage severity and extent.EstimateP valueSeverityTime#0.20NSAutoantibody group1Negativereference--Antisynthetase-0.6NSIMNM1.6NSDM- specific-2.6**FHL-10.4NSAssociated0.7NSMMT score1-0.1***ExtentTime#0.33NSCK, mkat/L2-0.006*#Time from diagnosis to MDI. *<0.05**<0.01***<0.0011.

Adjusted for disease duration + time.Results:Mean age at diagnosis was 54 years (SD 16), 205 were female (68%), median disease duration was 4 months (IQR 1-39). Clinical diagnosis and the autoantibody groups are shown in Table 1. The median time from diagnosis to the first MDI assessment was 2.2 years (IQR 1.2 – 5.5), 227 patients had a second MDI assessment at median 4.5 years (3.3-8.6 years) and 114 patients had a third assessment at 7.8 (5.8-9.9) years.Severity of damage:Only the DM-specific autoantibodies (P = 0.01) and manual muscle test score (MMT) (P = 0.007) were independent negative predictors; disease duration was a positive predictor (P = 0.01).Extent of damage: Autoantibodies were not significant predictors; creatine kinase (CK) levels were negative predictors (P = 0.01) (Table 2).Conclusion:Presence of DM-specific autoantibodies, a high MMT score over time and short disease duration seem to predict less damage severity whereas high CK levels seem to predict of less extent of damage. These findings indicate that some myositis specific autoantibodies may serve as predictors of damage along with other clinical measures.References:[1]Sultan SM, et al.

Abstract:

Equal Channel Angular Extrusion (ECAE) is used as a top down process to produce bulk nano/ultrafine grain structured materials by inducing high amount of strain with less experimental set up. In the present study AA 5083 alloy with circular and square cross sections are extruded at room temperature using two dies having cannels with circular and square cross sections respectively. Both the dies used in this study are having same channel angle (Φ)1200and outer corner angle (Ψ) 200. The circular and square billets are extruded for four times in route BC. The objective of this work is to study the effect of cross section of the billet, number of passes on grain refinement, mechanical properties and wear behaviour of AA 5083. Significant reduction in grain size is observed in extruded material using Field Emission Scanning Electron Microscope (FE-SEM) in the range of 80nm to 600nm after four passes. The microhardness in extruded materials is improved with no. of passes in both cross sectioned billets and it is more predominant for square billets even after two passes. The effect of dead zone is less in case of square billets and hence they have shown more structural homogeneity. The dry sliding wear tests are conducted to study the wear behaviour of the ECAEd materials. It is observed that the wear rate and coefficient of friction are reduced with number of passes in both the cases and rate of decrease is more in case of square billets.

Abstract:

In the present study, the wear behaviour of two aluminium alloys (AA-5754 and AA-5083) is analysed where these have been previously processed by severe plastic deformation (SPD) with equal channel angular pressing (ECAP). In order to achieve the objectives of this study, several disks made of these alloys are manufactured by isothermal forging from different initial states. The microstructures of the initial materials analysed in this study have different accumulated deformation levels. In order to compare the properties of the nanostructured materials with those which have not been ECAP-processed, several disks with a height of 6 mm and a diameter of 35 mm are manufactured from both aluminium alloys (that is, AA-5754 and AA-5083) isothermally forged at temperatures of 150 and 200 °C, respectively. These thus-manufactured disks are tested under a load of 0.6 kN, which is equivalent to a stress mean value of 18 MPa, and at a rotational speed of 200 rpm. In order to determine the wear values, the disks are weighed at the beginning, at 10,000 revolutions, at 50,000 revolutions and at 100,000 revolutions, and then the volume-loss values are calculated. This study was carried out using specific equipment, which may be considered to have a block-on-ring configuration, developed for testing in-service wear behaviour of mechanical components. From this, the wear coefficients for the two materials at different initial states are obtained. In addition, a comparison is made between the behaviour of the previously ECAP-processed aluminium alloys and those that are non-ECAP-processed. A methodology is proposed to determine wear coefficients for the aluminium alloys under consideration, which may be used to predict the wear behaviour. It is demonstrated that AA-5754 and AA-5083 aluminium alloys improve wear behaviour after the ECAP process compared to that obtained in non-ECAP-processed materials.

Abstract:

In this study, the effects of cold-rolling and annealing on the structural, electrochemical, and mechanical properties of AA5083 in a simulated seawater environment are investigated. The results demonstrated that annealing temperature significantly affects the alloy's mechanical and corrosion properties. According to potentiodynamic results, the rate of corrosion decreased after annealing. Compared to the cold-rolled sample, the heat treatment doubles the electrochemical impedance, indicating that the corrosion resistance of AA5083 alloy is suitable at 50°C annealing. Approximately twice as much ductility was added to the materials as compared to the as-received materials. Additionally, the mechanical testing revealed the Portevin-Le Chatelier (PLC) Effect Type B band, which reflected the smaller grain size.

Abstract:

Spot welding is a method of electrical resistance welding in which two or more metal sheets are clamped between two electrodes and at the same time an electric current is applied so that the surface of the material reaches the welding temperature and then the material is fused. The purpose of the study was to determine the tensile strength of the 5083 aluminum plate connection in the spot welding process. This research was carried out experimentally as for the plate material that is connected is aluminum AA 5083 which has a thickness of 1 mm. Before welding is carried out, it is necessary to determine the variation of parameters, namely the welding current of 1.75 volts, 2.20 volts, 2.28 volts and the welding time for 1 second, 1.5 seconds, and 2 seconds. The spot welding process is carried out by varying these parameters, with the shape of the connection that occurs is overlapping. After the splicing process, then the specimen is tested for connection strength through a tensile. From the results of the study, it was obtained that the greater the electric current used, the greater the electric power used and it can be seen that the longer the welding time, the greater the electric power used.

Abstract:

The use of aluminum alloys for external strengthening of reinforced concrete (RC) beams has been capturing research interest. Exposure to harsh environmental conditions can severely impact the strengthening efficiency. This works aims to investigate the degradation in the mechanical properties of aluminum alloy AA 5083 plates when exposed to temperatures ranging from 25 to 300 °C. Quasi-static Isothermal tensile experiments were conducted at different temperatures. It was observed from the experimental results that the yield strength remained constant in the temperature range of 25–150 °C before starting to drop beyond 150 °C, with a total reduction of ≈ 40% at 300 °C. The elastic modulus was temperature sensitive with about 25% reduction at 200 °C before experiencing a significant and pronounced reduction at 300 °C. The percentage drops in stiffness and yield strength at 300 °C were 62.8% and 38%, respectively. In addition, the Mechanical Threshold Strength Model (MTS) parameters were established to capture the yield strength temperature dependence. Two analytical models were developed based on the experimental results. Both models can reasonably predict the elastic modulus and yield strength of AA 5083 plates as a function of temperature. It was concluded that AA plates should be properly insulated when used as externally bonded reinforcement to strengthen RC beams.

Abstract:

An environment-friendly non-chromium chemical conversion coating was obtained from fluozirconate/fluotitanate acidic solution for the corrosion protection of AA 5083. The surface morphology, composition, electrochemical behavior and corrosion resistance of this coating were investigated. The coating was found to be a homogeneous and dense layer consisting of nano-size particles, of which the major component was compound oxides consisted by Al, Mg, Zr, Ti, F and O. The results of electrochemical measurements, immersion and natural salt spray (NSS) tests demonstrated that the corrosion resistance of the AA 5083 H-116 was improved by the nano-sized non-chromium chemical conversion coating considerably, which was most attributed to the great inhibitive action on the anodic dissolution by acting as a protective barrier layer.

Abstract:

The present work is an effort to study the influence of shot peening on the exfoliation corrosion behavior of aluminium alloy (AA) 5083. Surface textural changes induced by shot peening was characterized using microstructural and X-ray diffraction analysis. The surface roughness parameters were measured to study the benefits of peening induced surface topography. Further, the hardness survey was carried out to assess the severe plastic deformation on the peened layers. As a result, excellent resistance against exfoliation corrosion was achieved in the chloride environment. Shot peening plays major role in enhancing the corrosion resistance of AA 5083. In the absence of exfoliation attack, the unpeened sample surfaces such as ground, milled, and as received conditions end up with a significant pitting attack. The findings of this work will be useful for the aluminium alloy fabrications involved in the marine applications.

Abstract:

The aim of this paper is to investigate about the Portevin-Le Chatelier Effect (PLC) on a AA 5083 sheet. In order to study the minimizing of the PLC effect, three different rolling cyles have been carried out and an experimental campaign on the three different AA 5083 rolled has been carried out. In particular, the experimental campaign, to better understand the evolution of the phenomena during the rolling process, is based on: microstructural analysis, tensile tests and fractographic observations. Finally it has been found that the greater grain size the smaller the PLC effect, even if this effect cannot be totally removed, furthermore the PLC effect occurs only in the rolling direction. The best rolling cycle is the one that provide a hot rolling until 4mm, then a cold rolling up to 2mm and a final heat treatment of annealing.

Abstract:

In the present study AA5083 and AA6061 were welded using friction stir welding process by controlling the various welding parameters viz. rotational speed, welding speed and Tool axial force for two different tool profiles. Aluminum alloys 5083 and 6061 have similar properties and they both are widely used in marine industries and other transportation industries. In this work the effect of various parameters on the mechanical properties viz. tensile strength and impact strength were studied. In this study the Taguchi approach was used as a design of experiment to set optimum parameters. The experiments were done using Taguchi’s L9 orthogonal array. Analysis of variance test was also performed to obtain the effect of the parameters on the weld strength. Both DOE and ANOVA were performed using MINITAB software.
