Ceramic matrix composite (CMC) material systems are receiving a great interest to be used and provides unique properties for aircraft and land-based turbine engines, defence applications, rocket motors, aerospace hot structures and industrial applications. Boron carbide (B4C)-silicon carbide (SiC) ceramic composites are very promising armor materials because they are intrinsically very hard. Advanced SiC-based armor is desired such that the projectile is completely defetaed without penetrating the ceramic armor. The effect of B4C addition on microstructural and thermal properties of the SiC-B4C powder composites were investigated after high energy milling and hot pressing. SiC powders containing 5wt%, 10wt%, 15wt% B4C were mechanically alloyed in a high energy ball mill for 8 h. Microstructural characterization investigations (SEM, XRD) were carried out on mechanically alloyed SiC powder composites containing 5 wt%, 10 wt%, 15 wt% B4C powders and on these powder composites sintered in vacuum at 50 MPa at 2100 degree C. The thermal properties were characterized using DTA, TGA and dilatometer. The results were evaluated.
