| Abstract Scope |
The quality of components produced through hot isostatic pressing is strongly affected by powder characteristics, including purity, particle size distribution, and sphericity. Additionally, canning materials play a crucial role in determining the final product quality and must be carefully considered. This study investigated the problems associated with canning and its influence on mechanical properties such as hardness and tensile. 316H stainless steel powder was heat-treated and HIPed at 2300°F. The HIPed samples were micrographed and found to have different microstructures from the center toward the edge of the sample. The samples were quantitatively analyzed using nuclear reaction analysis and confirmed the carbon diffusion from canning material to the 316H stainless steel. The diffusion of carbon was found to influence mechanical properties such as hardness, yield strength, ultimate tensile strength, and ductility. These findings aim to underscore the importance of material selection and address the challenges associated with canning in HIP. |
