Abstract

The effects of rolling and annealing treatments on mechanical behaviors of AZ31 magnesium alloy thick plate under static compression loading were studied. The results showed that different third rolling deformation amounts within range from 5% to 30% and annealing temperatures from 250°C to 450°C have obvious effects on the compression strength. The magnesium alloy with smaller grain sizes exhibits higher strength values than those with larger grain sizes. The compression fracture metallurgy observation results exhibited that the fracture modes change from brittle to brittle-ductile mixture ones, corresponding to the thick plate under rolling treatment and under rolling and annealing treatments, respectively. With the increasing rolling amount and annealing temperature, the twinning number decrease.
