| Abstract Scope |
Powder Metallurgy Hot Isostatic Pressing (PM-HIP) is a critical manufacturing process that enhances the mechanical properties and dimensional stability of metal components by consolidating and eliminating internal defects. However, residual stresses induced during PM-HIP can significantly impact the final part's functionality and performance. This study investigates residual stress effects on PM-HIP-treated parts and proposes a method to optimize PM-HIP parameters to minimize these stresses.
The research simulates the geometry of PM-HIP components and analyzes residual stress distributions. By adjusting thermal and pressure profiles during the PM-HIP process, the study aims to identify optimal conditions that reduce residual stresses while maintaining mechanical integrity. Using a specialized Fortran simulation code, key findings reveal that the temperature profile during PM-HIP is crucial in determining residual stress levels. The study identifies an optimal temperature range where residual stresses are minimized, enhancing part functionality and improving manufacturing efficiency and reliability. |
