MANUFACTURING METHOD OF NANO OXIDE DISPERSION STRENGTHENER ALLOY AND NANO OXIDE DISPERSION STRENGTHENED ALLOYS PREPARED BY THE SAME

摘要

PURPOSE: A method for manufacturing nano oxide dispersion strengthened alloy and nano oxide dispersion strengthened alloy manufactured using the same are provided to simplify a manufacturing process using metallic elements instead of metal powder. CONSTITUTION: A method for manufacturing nano oxide dispersion strengthened alloy is as follows. Base metal and oxide formation metal are mixed and are fused(S1). The formed fused alloy is molded into a final form(S2). The alloy molding is heat-treated in a furnace with a temperature which is lower than the melting point of a metal element. Oxide is formed by supplying oxygen to the inside the alloy molding(S3).
