Preparation of Lamellar Multi-metal Composites by Selective Laser Melting and Melt Infiltration
Using Cu/316L as a model material,composites with delicate lamellar structure were prepared,and the effect of configuration variations on the properties of the composites was investigated.The results show that the properties of the lamellar composites are significantly anisotropic.With the increase in the thickness of the 316L layer from 200 μm to 1000 μm,the compressive strength and the elastic modulus of the composites increase,and the electrical conductivity slightly decreases,reaching 1.96,1.34,and 0.9 times of that of pure copper,respectively.Owing to the structural optimization(micron-scale laminations)and component selection(copper and stainless steel),the composites possess both outstanding toughness and good electrical conductivity.Moreover,the methodology provided in this work is novel and universal,providing a new approach for the design and preparation of high-performance and multifunctional composites.
