摘要: The present work deals with synthesis, microstructural and mechanical properties' evaluation of a metal matrix composite, produced by a combination of mechanical alloying and spark plasma sintering utilizing FCC CoCrNi medium entropy alloy as the matrix phase, with dispersion of Cr 5 B 3 particles. Cr 5 B 3 was formed in-situ, by the reaction of B 4 C, which was added to the powders prior to mechanical alloying, during sintering with Cr element present in the powders. The composite exhibited excellent tensile strength level …
