  • Process for the creation of uniform grain size in hot worked spinodal alloy
    Patent number: 9303304
    Abstract: Processes for producing a uniform grain hot worked spinodal alloy are disclosed. The processes generate a uniform grain spinodal alloy without cracking and without the need for a homogenization step. The processes include providing an as-cast spinodal alloy, heating the as-cast spinodal alloy between 1200 and 1300° F. for approximately 12 hours and hot working, allowing the spinodal alloy to cool, performing a second hot work on the as-cast spinodal alloy after it has been heated to 1700° F. for a defined time period, exposing the alloy to a third temperature, performing a second hot work reduction, and cooling the alloy again.
