The Impact of SLM Process Parameters on the Mechanical Properties of IN718 Alloy
摘要
The selective laser melting (SLM) process is utilized to fabricate IN718 alloy with scanning spacings of 0.04mm, 0.06mm, 0.08mm, and 0.1mm. The microstructure of the deposited and heat-treated alloys was examined using optical microscopy, Vickers microhardness testing, and electro-hydraulic servo high-speed tensile testing. The results demonstrate that SLM technology achieves excellent metallurgical bonding under varying process parameters. The microhardness of the alloy initially increases and then decreases with increasing scanning distance. Furthermore, the yield strength and elongation of the alloy increase as the scanning distance rises during high-speed tensile testing, indicating an enhancement in mechanical properties.
