Studies on Al–Cu–Li–Mg–Ag–Zr alloy processed through vacuum induction melting (VIM) technique
چکیده انگلیسی

A new technique of lithium addition has been adapted for the processing of Al–Cu–Li–Ag–Mg–Zr alloy, which gives more than 90% recovery of lithium throughout the billet. Processing studies on this alloy include casting, three step homogenization, to avoid incipient melting, and mechanical working particularly forging and rolling. The products in the form of sheets were subjected to various T6 (solution treatment + water quenching + aging) tempers. Mechanical properties were evaluated at room temperature and correlated with microstructure. Characterizations using optical microscope and post-fracture analysis have been carried out using Scanning electron microscope (SEM). Experimental investigation shows highest mechanical properties for the Al–1.3%Li alloy in T6 (500 °C/1 h + WQ + 190 °C/24 h) condition.
