Abstract:
     This invention provides a new type of nodular cast iron with vanadium, titanium and rhenium. The ferrite is obtained first through annealing, then biphase structure of ferrite and bainite is obtained through isothermal quenching. This material possesses good wear-resistance and high strength because of hard crystalline grains formed by vanadium and titanium. It also possesses high tenacity and low hardness because of a lot of ferrite. The machining performence is good. The parts made of this material are suitable in running with repeated loading and unloading or heavy slide friction.
