摘要： The present invention provides metal-based composite with oxide particle dispersion and a method for producing the same. The present invention relates to a method for producing metal-based composite with oxide particle dispersion, comprising sintering of metal-based ultrafine powders (with an average grain size of about 20 nm to 100 nm and a grain size distribution of about 5 nm to 300 nm and with the surface oxidized for handling) in vacuum, in an inert gas or in a reducing atmosphere by rapid sintering, crystallizing the ultrafine powders with a grain size of about 50 nm or less to metal oxide during sintering and simultaneously removing the oxygen on the surface of the ultrafine powders with the grain size of about 50 nm or more, and the metal-based composite with oxide particle dispersion produced according to the said method.
