Abstract
The present study is focused on rheological properties of PH1 stainless steel, produced by selective laser melting (SLM), at temperatures of hot deformation, with the aim to investigate the dependence of strain resistance on temperature and strain degree. The tests of cylindrical specimens, made of PH1 stainless steel, were carried out using a cam plastometer in temperature range 700 – 1200 °C at a strain rate ξ equal to 1 s-1 up to strain degree e equal to 0.8 – 1.2. The paper presents the results of investigation of initial microstructure, microhardness measurement and flow curves of PH1 steel, produced by SLM method. The flow curves of PH1 steel produced by SLM can be used in the development of new methods of manufacturing the metallic parts by additive technologies with the use of deformation post-processing.
