Abstract

The article shows the research of mechanical properties of specimens obtained by SLS frommetal powder composition of VGH159 alloy after long-term exposure at working temperatures. It has been shown that strength properties don’t decrease essentially after 500-hour exposure at 900С and plasticity reduction of the material have induced by the additional precipitation of phases with Cr and Mo and y'-phase from the solid solution. The comparison of the mechanical properties with passport characteristics of EP648-PS alloy have carried out. It was shown that VZh159 alloy surpasses that alloy in tensile strength at investigated temperature diapason.
