摘要

High density and crack-free TiC particle-reinforced Ni matrix composite (TPRNMC) samples were fabricated using selective laser melting (SLM). The TiC exhibited an atomic directly bonded interface directly bonded with the Ni matrix and distributed along the cell boundaries, resulting in a higher yield strength (YS, 1270 MPa) compared than that of the matrix alloy (831 MPa).
