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...

Cu-based ternary chalcogenides composed of earth-abundant and nontoxic elements are considered promising thermoelectric materials, although there few reports on them. In our previous studies, optimal mechanical alloying (MA) hot pressing (HP) were used to synthesize Cu3SbS4 (famatinite) Cu3SbSe4 (permingeatite). this study, solid solutions Cu3SbS4-ySey (y = 0–4) prepared using MA HP. X-ray diff...

Abstract The development of powder metallurgy methods in recent years has caused traditional casting to be replaced many industrial applications. Using such methods, it is possible obtain parts having the required geometry after a process that saves both manufacturing costs and time. However, there are material issues decrease functionality these including mechanical properties anisotropy great...

-A detailed experimental evaluation of mathematical models for densification during hot isostatic pressing (HIP) has been conducted using high purity copper powder as a model system. Using a new eddy current sensor, the density of cylindrical compacts has been measured/n situ and compared with model predictions for the HIP process. Pressure shielding by the can has been found to influence the d...
