(a) Low temperature and high stress
(b) High temperature and high stress
Figure 8: Creep performance comparison for the ERBO/1 superalloy between conventional heat-treated material and heat-treated material using the integrated HIP heat treatment. Two different creep regimes are compared: a) Low temperature and high stress and b) High temperature and low stress. [7]
