摘要：

A correlation between the proof stress ratio and ductility ratio is observed at different microstructural conditions in austenitic stainless steels. A general decrease in ductility ratio with increase in proof stress ratio is observed. In this short communication, earlier work is extended to the region of proof stress ratio less than one and ductility ratio greater than one by thermal ageing of a cold worked material and then by testing at elevated temperatures. The significance of this correlation is that the degradation in the tensile strength and ductility of the real structures can be carried out by simple and inexpensive tests such as uniaxial tensile tests.
