  • Long range ordered alloys modified by group IV-B metals
    Patent number: 4410371
    Abstract: Ductile long range ordered alloys having high critical ordering temperatures exist in the (V,M)(Fe,Ni,Co).sub.3 system having the composition comprising by weight 20.6%-22.6% V, 14-50% Fe, 0-64% Co, and 0-40% Ni, and 0.4-1.4% M, where M is a metal selected from the group consisting of Ti, Zr, Hf, and their mixtures. These modified alloys have an electron density no greater than 8.00 and exhibit marked increases at elevated temperature in ductility and other mechanical properties over previously known ordered alloys.
    Type: Grant

    Date of Patent: October 18, 1983
    Inventors: Chain T. Liu, Henry Inouye, Anthony C. Schaffhauser
  • Thorium doped iridium alloy for radioisotope heat sources
    Patent number: 4253872
    Abstract: A novel iridium alloy containing 100-500 ppm thorium has enhanced impact properties over undoped iridium and over prior art iridium alloys.
    Type: Grant
    Filed: February 16, 1977

    Inventors: Chain-Tsuan Liu, Henry Inouye, Anthony C. Schaffhauser, Calvin L. White
  • Fe-based long range ordered alloys
    Patent number: 4238229
    Abstract: Malleable long range ordered alloys having high critical ordering temperatures exist in the V(Co,Fe).sub.3 and V(Co,Fe,Ni).sub.3 system having the composition comprising by weight 22-23% V, 35-50% Fe, 0-22% Co and 19-40% Ni with an electron density no greater than 8.00. Excellent high temperature properties occur in alloys having compositions comprising by weight 22-23% V, 35-45% Fe, 0-10% Co, 25-35% Ni; 22-23% V, 28-33% Ni and the remainder Fe; and 22-23% V, 19-22% Ni, 19-22% Co and the remainder Fe. The alloys are fabricable by casting, deforming and annealing for sufficient time to provide ordered structure.
