Effect of the cooling rate during heat treatment and hot isostatic pressing on the microstructure of a SX Ni-superalloy
Single crystal Ni-based gas turbine blades show a combination of large casting pores and pores from the homogenization heat treatment. Both kinds of pores can only be reduced by HIP; however, HIP not only reduces porosity but also affects the size, number and morphology of γ′ particles. From the HI...
