strip and the influence of processing parameters, e.g. roll speed, casting temperature, and performed gap, on the microstructures and mechanical properties of as-cast magnesium alloy AZ31 is discussed. Based on this, the as-cast magnesium alloy strips have been cold-rolled directly for producing high quality strips. 2 Experimental A vertical-type twin roll caster was used to manufacture thin......
