Microstructure Evolution of TiC Particles In Situ

In this paper, a TiC reinforcement metal matrix composite coating is produced using nickel and graphite mixing powder on the surface ofTi-6Al-4V alloy by laser radiation. The microstructure of the coatings is investigated by XRD, SEM and EDS. Results show that most of the TiC phase is granular, with a size of several micrometers, and a few of the TiC phases are petals or flakes.

Jan 01, 2021 · The 316L stainless steels (SS) have become one of the most common structural materials in nuclear system applications due to their excellent physicochemical performance. Selective laser melting (SLM) preparation, mechanical properties, and irradiation resistance of 316L SS reinforced by second-phase particles have aroused extensive attention. Effect of the Particle Size of Cladding Materials on the Fe-based laser cladding layers were reinforced by TiC with different morphologies prepared in situ by using FeTi30 powder, graphite powder, and Fe-based self-fluxing alloy powder with different particle sizes. The effects of the particle size of the cladding alloy powder on the TiC morphologies, and the Effects of alloying elements X (Cr, Mn, Mo, Ni, Si) on the Feb 04, 2021 · TiC/316L stainless steel composite was prepared by selective laser melting (SLM). The effects of alloying elements X (Cr, Mn, Mo, Ni, Si) in 316L stainless steel on the stability of TiC (001)/-Fe (001) interface were calculated by the first principle. The results showed that alloy elements easily replace the Fe atom at the interface, and all of them have the tendency to segregate to the interface.
