Abstract

The evolution of the microstructure and texture of a newly developed Mg alloy Mg-6.9Sn-2.6Zn (TZ73) and its effect on tensile behaviour has been studied as a function of strain path change during hot rolling. The two strain paths employed are cross-rolling plus unidirectional rolling (CR-UDR) and reverse rolling (RR). The RR process led to a slightly higher fraction of dynamically recrystallized grains, slightly finer grain size, more uniform distribution of fine Mg2Sn particles, and weaker texture than the CR-UDR process. The RR processed sheet exhibited higher tensile strength and ductility in all the directions and less anisotropy in tensile properties than the CR-UDR processed sheet. The RR processed TZ73 alloy exhibited higher strength and ductility in the rolling direction than the other commercial and experimental rare earth-free hot-rolled Mg alloys reported in the literature.
