| Abstract Scope |
Hot isostatic pressing (HIP) has become an essential post-heat treatment to eliminate internal porosities and tailor microstructure for additively manufactured metal component performance improvement. In the present work, a finite element model based on creep and plasticity that is capable of pore closure evaluation was developed for the HIP cycle process window development. HIP soak temperature, soak pressure and initial pore size effects on pore evolution were investigated on Ti-6Al-4V additively manufactured components for model validation. The proposed model is effective in predicting pore evolution during the HIP process and provides a promising tool for additively manufactured components post-heat treatment process optimization. |
