Influence of TiO2 on Microstructure and Mechanical Properties of Al2O3p/Steel Matrix Composites Prepared by Squeeze Casting

By adding TiO2 powder into the preform, Al2O3 particles reinforced 1065 steel matrix composites were prepared by squeeze casting. The influence of TiO2 on the microstructure and mechanical properties of the c...
