چکیده
Hot isostatic pressing (HIP) technology can effectively reduce microstructure defects such as micropores, which are formed during solidification and hominization heat treatment, thus further improve the high temperature performance of nickel-based SX superalloys. This paper reviews application HIP treatment in superalloys, focusing on dislocation-creep closure diffusion-creep mechanisms kinetics annihilation micropores by HIP. The effects different scheme pore mechanical properties compared. advantages disadvantages schemes summarized. In addition, additive manufacturing (AM) superalloys is also discussed.

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 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 ...
