发明名称 Process for producing dispersoid-strengthened material
摘要 In a first embodiment the invention relates to a process for producing a dispersoid-strengthened material, comprising the steps of: (i) providing metal particles, wherein the metal is selected from platinum group metals, gold, silver, nickel and copper, as well as alloys thereof; (ii) mixing the metal particles with a precursor compound of the dispersoid and solvent; (iii) removing the solvent, so as to obtain metal particles provided with precursor compound; and (iv) compacting the metal particles provided with precursor compound in order to obtain the dispersoid-strengthened material, wherein the precursor compound is converted into the dispersoid during the compacting operation. In a second embodiment the invention relates to a process for producing a dispersoid-strengthened material, comprising the steps of: (i) providing metal particles, wherein the metal is selected from platinum group metals, gold, silver, nickel and copper, as well as alloys thereof, and wherein the metal particles are produced by mechanical processes selected from machining, milling, turning and filing; (ii) mixing the metal particles with a dispersoid or a precursor compound of the dispersoid, as well as solvent; removing the solvent; and compacting the metal particles obtained in step (iii) in order to obtain the dispersoid-strengthened material.
