Abstract

The present study is focused on rheological properties of AlSi10Mg aluminium alloy produced by selective laser melting (SLM) at temperatures of hot deformation with the aim to investigate the dependence of strain resistance on temperature, strain rate and strain degree. As-build cylindrical specimens made of AlSi10Mg aluminium alloy was examined on a cam plastometer in temperature range 20 - 500 °C, at strain rate ξ equal to 1, 10 s-1 up to strain degree e equal to 1.2. The paper presents results of study of initial microstructure, microhardness measurement and flow curves of AlSi10Mg alloy produced by SLM. The flow curves of AlSi10Mg alloy produced by SLM can be used in the computer simulation and development of new manufacturing methods of the metallic parts by additive technologies with the use of deformation post-treatment. © Published under licence by IOP Publishing Ltd.
