Because of its excellent properties, such as high strength, high module, wear resisting, and etc., sicp was added to ferroalloy as a reinforce phase. but the intrinsic difference between the bonds led to poor fabrication of the composites. in this paper, the effects of alloying, sintering, and heat - treatment on the properties and microstructures of sicp / ferroalloy - based composites were studied, : it was found that sic particles reacted with ferroalloy when sintered in 1100
