Abstract
The effect of carbon addition on the hot rolling behavior of as-cast AZ31 alloy was investigated. It is found that the carbon addition can refine the as cast grain size of the AZ31 alloy to 140μm. The edge cracking occurrence on the surface during hot-rolling of the AZ31 alloy was practically eliminated by the grain refinement. Based on the microstructure examination during the hot rolling, the improvement in rollability of the carbon added AZ31 alloy is attributed to the more homogeneous DRX process during hot rolling, which can distribute and effectively absorb strain energy and prohibit crack growth.
