Deformation and recrystallisation of BCC MG LI

Abstract

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 y fibre is weakened by higher rolling reductions, the a 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.
