摘要

Abstract

BSTRACTThe formation of microcracks at the interface of steel–copper heterostructures is prone to premature failure

which severely limits the application of heterostructure components. Herein

a new approach was proposed by doping nano-TiC in interface forming by laser powder bed fusion (L-PBF) to prevent the hot crack nucleation and block the solid-state crack propagation in steel–copper heterostructures . Benefitting from the TiC doping

the tensile strength of laminated steel–copper structures increased from 372 to 526 MPa. The findings of this research present a new approach to inhibit cracking in the fabrication of heterostructure component manufacturing using L-PBF.
