摘要

This investigation presents a selective laser melting strategy for fabricating high nitrogen-content Ti (Ti-N) materials. Unlike conventional cast Ti materials, Ti-N materials produced in this study exhibited a good balance of mechanical properties with an ultimate tensile strength of 976 MPa and 21.7% elongation due to solid-solution strengthening by N atoms originating in the Ti_2N layers covering pure Ti spherical particles.
