  • Method for refining microstructures of titanium alloy castings
    Patent number: 4612066
    Abstract: The microstructure of cast titanium alloy articles is improved by a method which comprises beta solution heat treating the article, followed by hydrogenating and then dehydrogenating the article.
    Type: Grant
    Filed: July 25, 1985
    Date of Patent: September 16, 1986
    Inventors: Lev Levin, Russell G. Vogt, Daniel Eylon, Francis H. Froes
  • Method to reveal microstructures in single phase alloys
    Patent number: 4548903
    Abstract: A method for revealing the microstructure of metal alloys which comprises the steps of polishing the sample, chemically etching the polished metal surface, thermally etching the chemically etched surface and quenching the thermally etched sample. This method allows observation of deformed and recrystallized grains on the same polished surface and provides the opportunity to correlate recrystallized grains to their nucleation sites.
    Type: Grant
    Filed: March 30, 1984
    Date of Patent: October 22, 1985
    Assignee: The United States of America as represented by the Secretary of the Air Force
    Inventors: Isaac Weiss, Francis H. Froes, Daniel Eylon
  • Method for refining microstructures of blended elemental powder metallurgy titanium articles
    Patent number: 4536234
    Abstract: A method for improving the microstructure of an article made by powder metallurgy of blended elemental titanium powder which comprises beta-solution heat treating the article at a temperature approximately equal to the beta-transus of the equivalent alloy, rapidly cooling the article, annealing the article at a temperature about 10 to 20% below the beta-transus and air cooling to room temperature. The resulting article has a fine alpha plate structure in a matrix of discontinuous beta phase.
    Type: Grant

    Inventors: Daniel Eylon, Francis H. Froes
  • Method for refining microstructures of prealloyed powder metallurgy titanium articles
    Patent number: 4534808
    Abstract: A method for improving the microstructure of an article made by powder metallurgy of prealloyed titanium powder which comprises beta-solution heat treating the article at a temperature approximately equal to the beta-transus of the equivalent alloy, rapidly cooling the article, annealing the article at a temperature about 10 to 20% below the beta-transus and air cooling to room temperature. The resulting article has a fine alpha plate structure in a matrix of discontinuous beta phase.

    Inventors: Daniel Eylon, Francis H. Froes
  • Method for refining microstructures of cast titanium articles
    Patent number: 4482398
    Abstract: The microstructure of titanium alloy castings is improved by a process which comprises beta-solution heat treating the cast article at or near the beta-transus temperature of the alloy, cooling the article to room temperature at a rate in excess of air cooling and aging the article at a temperature about 0.8 to 0.9 of the beta-transus.
