Patent number: 10858715Abstract: A dual hardness steel article comprises a first air hardenable steel alloy having a first hardness metallurgically bonded to a second air hardenable steel alloy having a second hardness. A method of manufacturing a dual hard steel article comprises providing a first air hardenable steel alloy part comprising a first mating surface and having a first part hardness, and providing a second air hardenable steel alloy part comprising a second mating surface and having a second part hardness. The first air hardenable steel alloy part is metallurgically secured to the second air hardenable steel alloy part to form a metallurgically secured assembly, and the metallurgically secured assembly is hot rolled to provide a metallurgical bond between the first mating surface and the second mating surface.Type: GrantFiled: September 26, 2018Date of Patent: December 8, 2020Assignee: ATI PROPERTIES LLCInventors: Njall Stefansson, Ronald E. Bailey, Glenn J. Swiatek

Patent number: 10260120Abstract: A process for reducing flatness deviations in an alloy article is disclosed. An alloy article may be heated to a first temperature at least as great as a martensitic transformation start temperature of the alloy. A mechanical force may be applied to the alloy article at the first temperature. The mechanical force may tend to inhibit flatness deviations of a surface of the alloy article. The alloy article may be cooled to a second temperature no greater than a martensitic transformation finish temperature of the alloy. The mechanical force may be maintained on the alloy article during at least a portion of the cooling of the alloy article from the first temperature to the second temperature.Type: GrantFiled: September 1, 2017Date of Patent: April 16, 2019Assignee: ATI PROPERTIES LLCInventors: Glenn J. Swiatek, Ronald E. Bailey
