| Abstract: | Based on the stress/strain behavior of a kind of Al-alloy at elevated temperature under statictension, It is pointed out that the hot tearing has the characteristic of apparaent brittle fracture but of plasticfracture in essential. The relation between the fracture mechcanism and the mechanical properties is revealedthrough the SEM analysis of the tensile fractures. |
