Abstract Scope |
Additive manufactured (AM) metals such as 316L stainless steels and Ti-6Al-4V (Ti64) alloys often have microstructural length-scales that span several orders of magnitude. It is thus of tremendous challenge to understand the deformation behavior of these materials at multiple length-scales. This presentation will report our recent effort to explore the deformation mechanisms of two commonly studied AM alloys (316L and Ti64), via in situ synchrotron x-ray diffraction mechanical testing. The influences of micro-residual stresses and porosities on tensile behavior are investigated. We discuss the implications of these results to the practical applications of these materials, and elaborate mitigation strategies to these issues encountered in laser power-bed-fusion additive manufacturing. |
