ALLOY MATERIAL IN WHICH ARE DISPERSED OXYGEN ATOMS AND A METAL ELEMENT OF OXIDE-PARTICLES, AND PRODUCTION METHOD FOR SAME

摘要

According to one embodiment of the present invention, an alloy casting material is provided. The alloy casting material comprises a base metal and an alloying element, and nanometer-sized oxide particles break down in the base metal such that a band structure or a network structure is formed by a novel phase comprising the alloying element and the metal element constituting the oxide particles, and the alloying element and the metal element have a negative heat of mixing relationship, and oxygen atoms formed by breakdown of the oxide particles are dispersed in the base metal and do not form oxides with the base metal.
