Effect of Hot Rolling on Microstructure and Texture Evolution of Mg-Li Based Alloy

Mg-Li based alloy, namely Mg-9%Li-5%Al-3%Sn-1%Zn (LATZ9531) was cast and consequently hot rolled at ~573K. In the present study, as cast and hot rolled structural features has been investigated by scanning electron microscope and electron back scattered diffraction (EBSD). Phase analysis revealed presence of major Mg-rich α-phase and Li-rich β-phase. Significant crystallographic texture evolution due to conventional hot rolling process was observed due to the increased activity of the non-basal slip mode.
