  • Method of manufacturing tough and porous getters by means of hydrogen pulverization and getters produced thereby
    Patent number: 4839085
    Abstract: A method of manufacturing high-zirconium getters that involves hydrogen pulverization of an entire alloy ingot or ingot pieces. The method offers distinct advantages over techniques that use mechanical means of powder production. The method is useful expecially in the manufacture of tough porous getters, of high Zr-content Zr-V alloys that have minor additions of elements such as Fe, Ni, Mn and/or Al.

  • Formation of intermetallic and intermetallic-type precursor alloys for subsequent mechanical alloying applications
    Patent number: 4668282
    Abstract: A method for forming intermetallic and intermetallic-type precursor alloys for subsequent mechanical alloying applications. Elemental powders are blended in proportions approximately equal to their respective intermetallic compounds. Heating of the blend results in the formation of intermetallic compounds whereas lack of heating results in intermetallic-type powder without the intermetallic structure. The resultant powder is then blended to form a final alloy. Examples involving aluminum-titanium alloys are discussed.
