Neural Observer for the Hot Isostatic Pressing
Hot Isostatic Pressing (HIP'ing) is one of several processes used for consolidating porous materials (such as metal powders) to high density. The equations describing the HIP'ing system dynamics are immensely complicated and highly nonlinear, thus complicating any controller design for the system. Further complications arise due to the fact that one of the system's states, grain size, cannot be...
متن کاملSensing a N D Modeling of the Hot Isostatic Pressing of Copper Pressing
-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...
متن کاملEffects of Temperature and Pressure of Hot Isostatic Pressing on the Grain Structure of Powder Metallurgy Superalloy
The microstructure with homogeneously distributed grains and less prior particle boundary (PPB) precipitates is always desired for powder metallurgy superalloys after hot isostatic pressing (HIPping). In this work, we studied the effects of HIPping parameters, temperature and pressure on the grain structure in PM superalloy FGH96, by means of scanning electron microscope (SEM), electron backsca...
متن کاملEFFECTS OF HOT ISOSTATIC PRESSING ON THE TENSILE PROPERTIES OF A356 CAST ALLOY
The influences of age hardening and HIP (Hot Isostatic Pressing) on the mechanical properties of A356 (Al 7Si 0.6 Mg) casting alloys were studied. Cast bars were homogenized, heated and maintained at a temperature of 540°C for a duration of 2 hours, followed by rapid cooling in a polymeric solution. The castings were age hardened at 180°C for a duration of 4 hours before being subjected to HIP ...
متن کاملBiomimetic evaluation of β tricalcium phosphate prepared by hot isostatic pressing
Two types of completely densified β-TCP tablets were synthesized from a stoichiometric β-TCP powder. The first ones (TCP) were conventionally sintered, while the second ones (TCP-T) were sintered and treated by hot isostatic process (HIP). The HIP produced completely densified materials with relative densities greater than 99.9% and a transparent appearance of tablets. Samples were immersed in ...
