Selective Laser Melting of Stainless Steel with Subsequent Processing

Abstract:

In this work we describe the results of selective laser melting of stainless steel. The obtained samples were processed by hot isostatic pressing. Metallographic study of samples obtained after selective laser melting and hot isostatic pressing procedure was conducted. Comparison of the structure of obtained samples and a significant decrease in porosity after hot isostatic pressing was registered. The results of the phase composition by X-ray diffractometry are presented. Identified significant structural and phase changes at the study of a surface of the obtained microsections of samples, and a change in the hardness of the samples were recorded.
