DEFORMATION AND RECRYSTALLISATION OF BCC MG LI

摘要

This paper describes a series of warm rolling and annealing experiments done on Mg14%Li, a bcc alloy which deforms most probably by slip on {110} and {112} planes. The rolling textures are different to IF and ULC steels given similar treatments in that the γ fibre is weakened by higher rolling reductions, the α fibre barely reaches {111}< 110 >, and a new fibre {100}< hkl > is clearly formed. Annealing the alloy after 90% rolling produces a component near {554}< 225 >, plus an equally strong {100}< 310 > and a subsidiary component near {411}< 148 >. The origins of these recrystallization textures is not known because it has proved very difficult to prepare metallographic samples due to the high surface reactivity of the alloy.
