Effects of Ti2SnC MAX Phase on Microstructure, Mechanical, Electrical, and Wear Properties of Stir‐Extruded Copper Matrix Composite

“…The formation of residual dislocation loops around each particle produces back stress that impedes dislocation migration, resulting in significantly increased yield strength by the Orowan mechanism. [ 41 ]…”

“…The formation of residual dislocation loops around each particle produces back stress that impedes dislocation migration, resulting in significantly increased yield strength by the Orowan mechanism. [41] Ti 2 SnC particles in the copper matrix cause the creation of new nuclei in the matrix during FSBE and simultaneously prevent the growth of recrystallized grains by the Zener pinning effect. The uniform distribution of Ti 2 SnC particles can significantly affect the grain refinement of Cu-Ti 2 SnC composites.…”
