Abstract Scope |
Heat treatment is a critical post processing activity that influences the nature of the microstructure formed, and it is well known that the microstructure affects the material's mechanical properties. It has been reported that if 3D printed component and a traditionally manufactured component of the same material are both subjected to the same heat treatment, they do not respond the same in relation to their material characteristics. Therefore, this study investigated the effect of heat treatment on 3D printed and casted 17-PH stainless steel material characteristics (microstructure, corrosion, and mechanical properties). The aging temperature was varied from 400-500 ℃. It was found that the casted 17-4 Ph had higher grain size than the 3D printed 17-4 PH, resulting in the former being more corrosion resistant than the latter. Finally the 3D printed 17-4 PH had superior mechanical properties as opposed to t casted 17-4 PH. |
