He has made significant contributions to the field of superalloys, holding 2 patents that showcase his expertise and innovative spirit. His work primarily focuses on methods that enhance the mechanical properties of superalloy articles.
Latest Patents
One of his latest patents is titled "Method for producing crack-resistant high strength superalloy articles." This patent describes a method of heat treating articles cast from a nickel-base superalloy, such as INCONEL 939.TM. The process involves selective heating to dissolve chromium and carbon nuclei in the crystal lattice, followed by selective cooling to form discrete chromium carbide nuclei along the grain boundaries. This innovative method results in articles with improved mechanical properties.
Another significant patent by Hatala is "Pre-HIP heat treatment of superalloy castings." This patent outlines heat treatments that enhance the results of subsequent Hot Isostatic Pressing (HIP) treatments. The described heat treatments effectively eliminate low melting phases that can cause gas entrapment during the HIP process. The articles are heated to a temperature just below the intended HIP temperature for a duration sufficient to reduce these problematic phases.
