Latest Patents

Seiji Takeishi holds a patent for a manufacturing method for oxide-dispersed alloys. This method involves several key steps: first, manufacturing alloy powder or an alloy wire rod consisting of a matrix metal and an additive metal. Next, the additive metal is oxidized in the alloy powder by water, forming dispersed particles through agitation in a high-energy ball mill. Finally, the alloy powder or wire rod is molded and solidified after oxidation. This invention is particularly beneficial for creating oxide-dispersed alloys where the free energy of oxide formation of the matrix metal is higher than the water standard free energy of formation, while the free energy of oxide formation of the additive metal is lower.
