PRODUCTION OF AL2O3 ODS CU POWDER USING CU-AL PREALLOYED POWDER AND ITS METHOD

摘要

The present invention relates to a dispersion strengthened copper alloy powder, copper alloy powder such as copper powder dioxide Materials copper-aluminum dioxide, but configured as a copper powder and copper alloy powder, - the molar ratio of the aluminum component employed in the aluminum alloy powder (copper dioxide: aluminum) 3-5: 1-3 in a total amount of stirring in the raw material charged to the mixer mixing and stirring the ingredients see-charged to the ball mill, and then was sealed under an inert atmosphere - are molded to induce a mechanochemical reaction was added to mechanical energy by the mill. With this invention a copper-aluminum alloy powder can be obtained than a fine and uniform distribution of aluminum oxide to be able to control the rate of substitution reaction by using copper and aluminum dioxide as the reactant for the formation of an aluminum oxide, a wide range of composition can be prepared with aluminum oxide dispersion strengthened type alloy, it is possible to prevent that especially by the non-uniformity in the microstructure of strip without a dispersion (Layer) is formed.
