Abstract

Abstract

This article gives a method by which the thermal faiigue resistance of engineering materials can be measured through spherial specimen. The pare-meters of upper temperature T, cylc time n and fracture depth d are recommended as the quantitative indexes of measuring the thermal fatigue resistance of engineering materials. Three kinds, thirteen specimens were tested using this method and the test result have proved the feasibility of the method.
