Abstract:

I ENTIFIERS Hastelloy R-235, Ductility. Longitudinal strips of 10 cold worked Hastelloy R-235 nickel base alloy were exposed to 1500 F for 10, 30, 50, 70 and 100 hour periods in an air furnace. After exposure the strips w re prepared and tension tested at room temperature. The mechanical properties versus exposure time at 15 0 F showed that the material u derwent aging during exposure T e ging peak was reached at some tim prior to 10 hours at 15 F Ov r aging effects were observed at all exposure times greater than 10 hours.
