Hot isostatic pressing (HIP)
The HIP process involves very high pressures (p = 100 MPa) and very high temperatures (T ˜ 1200 °C). Castings are subjected to hot isostatic pressing to close small cavities (pores) resulting from the casting process and to improve the component strength and service life.
