This work, models the compaction of a dispersed body under conditions hot isostatic pressing (HIP) cycle using example manufacture compacts from VZh159ID powder and Inconel alloy 718. For research, fraction -70 + 25 μm, bulk density 3.77 g/cm3 (4.83 after tapping), fluidity 2.3 g/s, specific surface area 446 cm2/g, average particle size was used according to Fisher 16 microns, as well 718 -315 ...

Power metallurgy hot isostatic pressing (PM-HIP) is a manufacturing technique capable of producing net shape or near-net components with complicated geometries from materials that are difficult to melt and cast, mechanically deform weld. However, the process soundness outcome extremely sensitive geometric design capsule (also known as die can) used in process. The for each new component involve...

This study investigated the effects of the hot isostatic pressing process on the crack healing, microstructure, and mechanical properties of the laser repair-welded CM247LC precipitation-hardened superalloy. To ensure the strength of the repair-welded area, this study used the direct re-melting approach, and simulated the repair welding with the filler addition, which has a chemical composition...
