Abstract

Hounsfield impact tests have been carried out on specimens machined from the gauge lengths and grips of type 316 weld metal creep-ruptured test pieces. The room temperature impact strength of type 316 weld metals is reduced by post-weld heat treatment at 800°C, whereas solution heat treatment at 1050°C greatly improves the impact strength relative to the aswelded condition. The room temperature impact strength is generally reduced by stress-free ageing at 600°C. Stressed ageing causes further reduction in impact strength relative to specimens which have undergone unstressed ageing. This effect is probably caused by the enhanced rate of precipitation in the gauge lengths of the creep specimens. © 1991.
