  • Method for heat treating cast titanium articles to improve their mechanical properties
    Patent number: 4631092
    Abstract: Cast titanium alloys and a method of heat treating the alloys in order to obtain fatigue and mechanical properties comparable to wrought titanium is disclosed. The heat treatment is practiced by solution heat treating a cast titanium article above its beta transus, rapidly cooling, stabilizing at a temperature within the alloy's alpha/beta phase range, and finally aging the article to achieve the desired properties.

  • Mold and method for casting of fragile and complex shapes
    Patent number: 4556528
    Abstract: A method and apparatus for casting of fragile complex shapes by the formation of a two layer wax mold about a pattern of the shape to be cast. Thereafter, the pattern is removed from the mold and the outer layer of wax dissolved. The slip is then poured into the mold and allowed to solidify before the inner layer of the mold is completely removed from the cast article.
