TEXTURE EVOLUTION DURING THE STATIC RECRYSTALLIZATION OF THREEBINARY MG-Y ALLOYS

摘要

The evolution of texture during the static recrystallization of three cold rolled binary Mg-Yalloys was characterised using electron backscattered diffraction (EBSD). It had been shown inprevious studies that alloys that contain yttrium can develop more random texture, during thermo-mechanical processing and this can reduce or eliminate the yield asymmetry common to wroughtmagnesium alloy. The three alloys were initially hot rolled to break up the as cast structure thencold rolled using multiple passes of 1% reductions to avoid cracking and impart a high attainable
