Cracking inhibition of nano-TiC reinforced René 104 superalloy fabricated by selective laser melting
TL;DR: In this article, a nano-TiC reinforced Rene 104 superalloy was fabricated by selective laser melting (SLM) and the grain refinement and columnar-to-equiaxed grain transition was promoted as a result of the heterogeneous nucleation provided by TiC nanoparticles, and the cracking density of as-printed TiC-Rene 104 was reduced by 83.3% and the ultimate tensile strength and elongation were improved by 31.3%.
