This is a report on discussions at VAMAS-LCF Committee of The Iron and Steel Institute of Japan. The aim of VAMAS Low Cycle Fatigue project is to examine the effects of test variables on high temperature fatigue tests. In Japan ten laboratories participated in the round robin tests. Based on the discussion of international and domestic test results at the committee, solutions were sought to certain problems on high temperature low cycle fatigue testing and recommendations for methods of testing were made. Investigation was made of the following. One is the effects of a spot-welded thermocouple on test results and alternative methods for temperature measurement, and the other is physical meaning of the number of cycles to failure in high temperature low cycle fatigue.
