Abstract
The influence of stress on the microstructural stability of type 316 s tainless steel weld metal at high temperatures has been examined using the gauge section and shoulder region of creep specimens treated at 8 23, 873, and 923 K. M(23)C(6) carbide and the intermetallic phase sigm a have been observed in optical metallography and X-ray diffraction an alysis of the extracted precipitates. The amount of precipitation in t he gauge section was generally found to be more than to be more that i n the shoulder region. The application of stress was seen to enhance t he precipitation kinetics of the sigma phase.
