OSTI ID:4205054
The effect of creep to 2% in 100 hours at temperatures from 600 to 900 deg F was determined on the tension, compression, and tension-impact properties of 17-7 PH stainless steel (RH 950 Cond.) at room temperature or the exposure temperature. A substantial loss in ductility was observed in room temperature tension tests. Material exposed to creep at 600 deg F exhibited a substantial Bauschinger effect in tension and compression tests. The loss in ductility is attributed to stress and/or temperature induced aging during the creep-exposure. (auth)
