报告题目(中文)：Solidification Cracking in Welds of Aluminum Alloys
报告内容简介：Cracking can occur during solidification of Al alloys in both welding and casting. Key aspects of solidification cracking in Al welds will be presented in two parts. The first part is the introduction to solidification cracking in Al welds, including the characteristics of cracks, crack susceptibility tests and reduction of cracking. The second part is the prediction of crack susceptibility. An index for predicting the crack susceptibility of Al welds recently proposed by UW-Madison will be discussed. The index is the maximum │dT/d(fS)1/2│ of an Al alloy, where T is temperature and fS the fraction of solid. The higher the index, the greater the tendency to crack. Curves of T vs. (fS)1/2 of Al alloys can be plotted to find the maximum steepness │dT/d(fS)1/2│ using commercial thermodynamic software package Pandat and Al database PanAluminum.
