Abstract Scope This research work examines the mechanical behavior of 15Cr-5Ni stainless steel parts produced by direct metal selective laser sintering (DMLS). The main objective of this research is to identify the influence of low-temperature precipitation hardening on tensile properties and fracture toughness of DMLS fabricated specimens. Test specimens are fabricated according to ASTM E8/M8 and ASTM E399 standards using EOS M250 laser sintering machine. Following DMLS specimens subjected to precipitation hardening for 1 hour at a temperature of 486 °C. To evaluate the influence of heat treatment on mechanical properties of DMLS produced parts the experimental trailers including, tension test and linear-elastic plane-strain fracture toughness are performed at the room temperature. Furthermore, microscopic observation of fractured surface is performed to study the failure mechanisms in more detail. The outcomes indicated that post-DMLS heat treatment improves mechanical properties in the terms of yield stress, young modulus, and ultimate strength. However, this process has a negligible negative effect on the ductility. Moreover, the fracture toughness test results indicate ductile fracture mechanism in the DMLS produced specimens while the specimens are subjected to precipitation hardening demonstrates brittle fracture.
