“…The selection of SHT temperature and time is referred by Al-Mg phase diagram. 28 From this phase diagram it suggests that the selected SHT parameter is suitable to obtain the homogenized grain structure of the alloy. In literature, 29,30 following kinetics of precipitation sequences during SHT of Al-Mg alloys has been reported SSSa !…”

In present work, cryorolling is performed to obtain the higher mechanical strength of the received material. Close to 50% and 30% increments in tensile and yield strengths of the material are observed for 40% thickness reduction. However, limited ductility has been obtained for cryorolled samples. Post annealing heat treatment is performed on cryorolled samples to obtain combined enhancement in strength and ductility of the alloy. Difference in the ductile fracture along with crack initiation and its advancement with plastic straining is also compared for cryorolled and annealed cryorolled samples. Fracture angle and crack propagation behavior at vicinity of gauge section is evaluated by using extended finite element method (XFEM) and compared with experimental tested work piece. XFEM has been adopted to simulate the crack growth behavior from nucleation till fracture of the investigated alloy. Triaxial stress contour plots are also captured by XFEM near to the crack initiation zone.

This study concentrated on the degradation and wear characteristics of nanocomposites reinforced with (0, 0.5, 1.5 and 2.5 wt.%) titanium dioxide (TiO2) nanoparticles on the AZ31 Mg alloy fabricated by the stir casting method. Optical microscopy and FESEM images showed that the TiO2 nanoparticles were distributed uniformly and the intermetallic phase Mg17Al12 observed along the grain boundaries. The surfaces of the nanocomposite samples was gradually covered with a magnesium hydroxide (Mg(OH)2) protective layer after 48 h of immersion in simulated body fluid (SBF). The immersed composite samples contained several white hydroxyapatite and magnesium phosphate particles. The addition of up to 1.5 wt.% TiO2 nanoparticles reduced the degradation rate of the nanocomposites in SBF, while further addition increased it. FESEM images of the immersed samples revealed the presence of corrosion pits and cracks on the AZ31 alloy and its nanocomposites. Under dry conditions with varying loads, the wear characteristics of fabricated nanocomposites were studied using computerised pin-on-disc equipment. The addition of TiO2 nanoparticles up to 1.5 wt.% improved the wear resistance of the nanocomposites. However, the further addition increased the coefficient of friction (COF) and wear loss due to agglomeration and porosity in the nanocomposites. The FESEM morphology of the worn surface revealed that abrasion was the primary wear mechanism at low loads, and abrasion with severe plastic deformation was dominant at higher loads.
