Microstructure, solidification behavior and mechanical properties of Al-Si-Mg-Ti/TiC fabricated by selective laser melting

, 2020
Ball-milled Ti/TiC composite particles (TiC nanoparticles assembled on Ti microparticles) were designed, prepared, and mixed with Al-Si-Mg powder to fabricate an Al-Si-Mg-Ti alloy with TiC nanoparticles (Al-Si-Mg-Ti/TiC) by selective laser melting (SLM).

Microstructure and properties of laser cladded B4C/TiC/Ni-based composite coating

International Journal of Refractory Metals and Hard Materials, 2020
In order to study the effect of TiC/B4C ceramic particles on the microstructure evolution and microhardness of Ni204-based cladding coating, TiC/B4C/Ni204-based composite coatings were fabricated by laser cladding. The results showed that the TiC ceramic
