Cracking during solidification is a serious defect in welding and casting. The crack susceptibility of one Al alloy relative to that of another has been predicted recently using the maximum steepness |dT/d(fS)1/2| as the crack susceptibility index, where T is temperature and fS the fraction solid. T...
