Effect of TiC Nanoparticles on the Mechanical Properties of a K465 Superalloy

Abstract

In this paper, the effects of TiC nanoparticles on the mechanical properties of the K465 superalloy were investigated. The elongation of the K465 alloy was improved by adding TiC nanoparticles without ultimate tensile strength reduction. Adding TiC nanoparticles can also effectively refine grain size and influence dendrite morphology. Moreover, the addition of TiC nanoparticles also led to the change of carbide morphology. The improvement of elongation was attributed to the refined grains and changed the morphology of carbides.
