内容简介

The sonic velocity and porosity of AG material subjected to thermal shock were measured using an ultra sonic pulse-echo method, and at the same time the equivalent stress was measured by stress analysis methods. The relationship between the measured physical values and equivalent stress was investigated. The followings points were clarified: as the equivalent stress increased the sonic velocity remarkably decreased and damage in the range of tensile stress was larger than that in the range of compression stress.
