PURPOSE: To obtain the titled composite in which ceramics are dispersed uniformly, by heating mixture of mother phase iron metal powder and ceramic powder or fiber, press molding said mixture under the state in which mother phase metal is half melted, to strengthen the adhering strength of said both components.
CONSTITUTION: Metallic powder to form mother phase iron metal is composed of metal powder easy for obtaining half melted state, and metal powder for adjusting whole compsn. of mother phase metal in relation to said metal powder. These metal powder and powder or fiber of ceramic (contg. carbide, nitride, oxide, etc. of metal) are mixed. Next, said mixture is heated and press molded under the state in which solid and liquid coexist in 5W50% liquid phase vol% against whole of the mixture. As the result, adhering strength of mother phase iron metal with ceramic is raised, pore is eliminated, ceramics are dispersed uniformly. Lower heating temp. in this case compared with that of conventional casting method can be used, and composite material having sufficient strength is obtd. especially even in air.
