Abstract
There is a limit to rolling of Ni-base superalloy IN-100 at the temperature range room temperature1 250°C because of about 60% γ' volume fraction.
In a series of our experiments, however, it was shown that powder-consolidated Mod. IN-100 by hot isostatic pressing could be rolled at the temperature range 850950°C. Tests were carried out with powder-consolidated Mod. IN-100 to make clear quantitatively the effects of rolling reduction, annealing temperature and annealing time on the recrystallization. Furthermore, it was shown that Mod. IN-100 as powder-consolidated was possible to become superplastic and its total elongation exceeded 300% over a suitable range of temperature and strain rate.
