This study aims to prepare a stir-cast EV31A magnesium alloy and investigate the effects of T4 condition (solid solution strengthening) T6 strengthening cum age hardening) on phases, microstructure, mechanical properties, fractography. The solid at 520 °C for 8 h allows Rare-Earth Elements (REE) dissolve in Mg matrix, but solubility is limited by presence Zn. phenomenon responsible heat-treated...

Friction stir welding is advance joining process for different similar and dissimilar metals. It is commonly used for joining of Aluminium alloys. In this study an attempt were made to join commercial structuralaluminium with 7039 aluminium alloy. A zig-zag pattern of hardness was found in weld nugget. Microstructural characterization and fractography of joints were examined using optical and s...
