Effect of Heating Temperature of Quenching on the Properties of TiCp/Fe Composite
In-situ TiC particle reinforced iron based composite was further processed using quenching, and the effect of heating temperature of quenching for the properties of TiCp/Fe composite was investigated. The quenching phases of the composite are as same as that of the as-cast composite. Quenching can further improve wear resistance of TiCp/Fe, and the composite via quenching route is more suitable for the application of light load. When the optimum heating temperature of quenching of TiCp/Fe is equal to 780 °C, the microstructure of the steel matrix is fine martensite (M), as well as the composite has the highest hardness and wear resistance. The lower or higher heating temperatures of quenching process all result in the decrease of hardness of the steel matrix, which leads to the wear resistance being lower than the as-cast composite.
