Effect of Heat Treatment on Microstructures and Hardness of SiC/Steel Armor Composite

Article Preview

Abstract:

The SiC reinforced ferrous based armor composites were treated with three heat treatments of annealing, isothermal quenching and annealing. The relationships between the treatment processing and the microstructures and hardness of the composite material were investigated. The results revealed that the heat treatment had scarcely any influence on the reinforced component but there appeared iron silicide existing at the interface of the two component, and the hardness of the component changed in three same treatment situation, the highest hardness of the matrix reached 532HB after subjecting to the isothermal quenching at 300°C.
