Tensile properties and microstructure of Alloy 718 thermally aged to 50,000 h
Conference
·
OSTI ID:5622357
Samples of Alloy 718 given the standard heat treatment were thermally aged from 538 to 704{degrees}C for times up to 25,000 h and aged at temperatures of 593 and 649{degrees}C up to 50,000 h. Tensile properties and microstructures of these samples show that extending the thermal exposure form 25,000 to 50,000 h at 593 and 649{degrees}C has very little additional effect, and further illustrates the long time stability of this aged hardened alloy. 5 refs., 8 figs., 1 tab.
