Abstract
Abstract A mold member and a rapidly solidifying water cooled rotary roll member contain 1.3 to 5% of Ni, 0.2 to 2% of Ti, 0.1 to 1.5% of Cr, 0 to 0.5% of Zr, 0 to 1% of Al, 0 to 0.5% of at least one of Fe and Co, 0 to 1.2% of Sn, 0 to 1.2% of Mn, 0 to 1.2% of Zn, 0 to 0.2% of Mg, 0 to 0.2% of P, and 0 to 0.2% of a rare earth element, wherein the remainder of the material has a composition consisting of Cu and unavoidable impurities. Each of the members has superior thermal fatigue resistance and erosion resistance against molten metal, high-temperature strength, high-temperature hardness, high-temperature ductility and heat resistance.
