抄録

In order to define the change of mechanical property owing to stress relief heat treatment, HT60 base metal and welded joint were subjected to S.R. treatment with or without restraint jig which induced tensile residual stress. Tensile test and impact test were carried out using specimens which had been machined out from test assembly after S.R. treatment. Results indicate the following findings, <BR>1. Tensile and yield strengths of base metal showed small drop due to S.R. treatment at 600°C. But impact property did not show any change.<BR>2. Impact property of heat affected zone indicated a tendency to be improved by S.R. treatment, especially when temperature was 600°C.<BR>3. The existence of residual stress did not show any effect on the change in impact property of weld bonded region owing to S.R. treatment.<BR>4. Effect of cooling rate in S.R. treatment on impact property of weld bonded region was not recognized in the region between 50°C/hr and 250°C/hr.
