Densification behavior of TA15 alloy powders during hot isostatic pressing
Source abstract
Abstract
Numerical simulations of hot isostatic pressing (HIP) were conducted to investigate the densification behavior of Ti-6.5Al–2Zr–1Mo–1V (TA15) alloy powders. The densification model proposed by Shima was implemented into the finite element software MSC.Marc and validated against experimental results. The simulated density distribution showed good agreement with experimental measurements. Based on this validated model, the effects of HIP temperature and pressure on densification were systematically analyzed using response surface methodology (RSM), enabling the identification of optimal processing parameters for achieving full density. In addition, the influence of capsule thickness on the relative density and deformation behavior of the powders was investigated. The results indicate that when the capsule thickness exceeds 11 mm, the relative density of the powders decreases below 99%, highlighting a significant shielding effect of the capsule.
