Dear Prashanth Muralishankar,

As you know, the addition of Yttrium oxide reinforcement would improve the strength and hardness of the aluminium matrix through the grain refinement mechanism and load transfer mechanism.

A large number of residual dislocation loops generated due to the interaction between Y2O3 and dislocation would delay the plastic deformation of the strengthened Al matrix and yields a better compressive strength.

Thanking you
