Abstract Scope |
The continued development of metal additive manufacturing (AM) has expanded the metallic alloys for which these processes can be applied. However, rapid cooling rates inherent in AM have presented difficulties in producing crack-free parts. One possible solution is to use alloys that can accommodate the stresses developed during the build process. For example, transformation induced plasticity (TRIP) may not only resist cracking that has plagued traditional AM of titanium alloys, but also promotes good combinations of strength and ductility with deformation. A better understanding of where and when TRIP occurs during AM is needed to exploit it. Simulated laser-powder bed fusion (L-PBF) of the beta-titanium alloy Ti-10V-2Fe-3Al (wt.%) was performed at the Advanced Photon Source at Argonne National Laboratory under varying conditions. TRIP was observed in the melt pools, and the effects of process parameters and scan strategy were determined through post-mortem microstructural characterization.
