White Paper - High Pressure Heat Treatment of AM Parts. Combining HIP and Heat Treatment

Hot Isostatic Pressing (HIP) has been used for several decades within different industries for a wide variety of applications. During the recent years HIP has become an important post process for metal additive manufacturing (AM) to secure material performance and quality. The HIP process uses a high isostatic pressure and elevated temperature to densify additively manufactured material by eliminating internal defects. The elimination of defects results in improved material properties such as fatigue, creep, ductility and fracture toughness. In many demanding AM applications, HIP is both a requirement and a necessity to achieve the required properties and material performance.
