| Abstract Scope |
Laser powder bed fusion (LPBF) additive manufacturing (AM) is an enabling technology but is currently hindered by limited availability of printable materials with high strength and ductility. In this study, we have printed a new high entropy alloy (HEA) that exhibits transformation induced plasticity (TRIP). Effect of various printing parameters, i.e. layer thickness, hatch spacing, power, and scan speed on part density, microstructure and mechanical properties have been evaluated. These parameters were optimized to obtain fully dense, homogenized material with minimal defects. The effect of parameters on the phase stability of HEA will be discussed and correlation of the mechanical response with microstructure will be presented. |
