  • Nickel beryllium alloy compositions
    Patent number: 9334551
    Abstract: Disclosed herein are nickel beryllium alloys having improved corrosion and hardness characteristics relative to known nickel beryllium alloys. The alloys have a chemical composition with about 1.5% to 5% beryllium (Be) by weight, about 0.5% to 7% niobium (Nb) by weight; and nickel (Ni). Up to about 5 wt % chromium (Cr) may also be included. The alloys display improved hardness and corrosion resistance properties.

  • Method for producing aluminum powder alloy products having improved strength properties
    Patent number: 4435213
    Abstract: Aluminum alloy atomized or other powder is compacted and shaped into a useful article including heating the compact rapidly by induction heating techniques. Such rapid induction heating results in improved strength or toughness properties without substantial penalty in elongation, thereby rendering the product so produced more useful in high strength applications. The product so produced may be subsequently shaped by forging, extruding or rolling processes.
