摘要	The present work investigates the interaction of the matrix and lamellar CrC carbide in a CoCrNiVC medium entropy alloy (MEA) during the plastic deformation. The homogenized sample was annealed to facilitate the precipitation of the carbide. The lamellar carbide only precipitated near the incoherent twin boundaries. Nanoindentation technique was used to introduce the plastic deformation in a local region near the incoherent twin boundaries. Interestingly, a new nano-grain was formed in the region containing carbide during the test. The lamellar carbide confined the propagation of the plastic strain, leading to a high strain gradient at the region between two lamellar carbides, which is substantiated by finite element simulation. Such a high strain gradient is responsible for the formation of nano-grain boundary in the present MEA with the lamellar carbide during nanoindentation.
