Abstract
Commercially pure (cp) molybdenum (Mo) is one of the high-temperature materials of immense potential. It has a body-centered cubic (bcc) structure so it is hard to fabricate using nonequilibrium processes such as the selective laser melting (SLM) without the formation of cracks due to its inherent brittleness. This study deals with the fabrication of dense and near crack-free cp-Mo samples produced by the SLM. The laser scan strategy is adjusted from a single scan to a double scan to reduce the solidification cracks. Samples produced with a laser double scan strategy show a density of ∼99% with a hardness of ∼222 HV.
