cast under ordinary conditions , but get a lot of crystal structure . Showing a white cast iron solidification structure similar to when the boron content is 0.59 to 4.13% when . Cast alloy Fe-CB -cast microstructure is dendritic matrix and the matrix distribution between the coarse dendrite , continuous network of a boride or a boron carbide crystals . Matrix organization is composed of pearlite , ferrite, a small amount of martensite . With boron , carbon content increases , the eutectic also increased to some extent , so the alloy hardness rising, but its toughness decreased. Which affect the boron content was significantly higher than carbon . To study the influence of heat treatment process Fe-CB alloy microstructure and properties of composite wear plates , and were carried out water quenching , water quenching and tempering, annealing and normalizing different temperatures . Heat Treatment results show that Fe-CB alloy , hardening, annealing, normalizing heat treatment methods , such as the hardness of the alloy Fe-CB obvious impact , but has little impact toughness . Cast alloy
