Present work focuses on developing a mechanism based strengthening model to predict the mechanical properties of age hardened Mg binary alloys. The study attempts to unify several model parameters and successfully demonstrates the ability of the model to predict the hardness and effective stiffness properties of aged Mg based binary alloys. The model considers the contribution of several strengthening mechanisms to estimate the hardness of Mg-Al and Mg-Zn alloy systems that are precipitation hardened at different aging conditions. The proposed model uses input parameters that are obtained from a precipitation model proposed by Paliwal and Jung (2019). Vickers micro-hardness experiments are conducted on aged binary Mg-Al (6 wt% Al) and Mg-Zn (4.0 and 5.5 wt% Zn) alloys. Verification and validation of the proposed model is carried out by comparing: (a) the hardness measures from experiments with model predictions, (b) the effective stiffness measures obtained from experiments with model predictions based on mean-field approach (Mori–Tanaka method) and (c) the model predictions relative to those obtained from experimental and theoretical data for Mg binaries in literature.
Polymer and polymer matrix composite materials are used in automotive applications owing to the high strength-to-weight ratio. However, the joining of polymer matrix composites is a challenging task due to the lower melting temperature, lower thermal conductivity, and agglomeration of reinforcements during fusion welding of these materials. Friction stir welding, a solid-state welding technology, is a suitable alternative for the welding of polymer matrix composites. The tool design, welding process parameters, and reinforcement content are some of the important factors that affect the material flow and microstructure in the welds. Several innovative modifications to conventional FSW, such as submerged FSW, heat-assisted FSW, friction stir spot welding, and friction riveting, have been suggested for defect-free welding of PMCs. Various weld properties such as tensile strength, hardness, shear bond strength, and impact strength have been studied for the FSW of PMCs. The weld defects have been analyzed and characterized. The numerical simulation of the FSW of PMCs has also been attempted by various researchers.
