Abstract

The initial coarse grain size of 400㎛ of a as-cast AZ31 alloy was refined to 130㎛ by carbon addition method. The microstructural evolution, recrystallization, edge cracking phenomena of the coarse grained AZ31 alloy during hot rolling were investigated and compared with those of grain refined AZ31 alloy.
