Patent number: 11613800Abstract: A method comprises providing a molten aluminum alloy selected from the group consisting of 6000 series aluminum alloys comprises chromium (Cr) in a range of between 0.001 wt % to 0.05 wt %. The molten aluminum alloy is formed into a formed body having beta-AlFeSi particles. The formed body is solution heat treated at a temperature in a range of 1,025-1,050° F. to form a heat-treated body. The solution heat treating transforms substantially all of the beta-AlFeSi particles into alpha-AlFeSi particles such that the heat-treated body is substantially free of the beta-AlFeSi particles.Type: GrantFiled: February 20, 2020Date of Patent: March 28, 2023Assignee: Johnson Brass & Machine Foundry, Inc.Inventors: Arvin Montes, Lance Johnson

Patent number: 6846369Abstract: A method for producing a cast aluminum alloy article having high strength and/or toughness is provided. The method includes providing a molten aluminum alloy, centrifugally casting the molten aluminum alloy to form a cast body; and hot isostatically processing the cast body to form a hipped body. The hipped body may optionally be solution heat treated to form a heat treated body, which may subsequently be precipitation hardened to further enhance the properties of the cast product as desired. The method allows the production of cast aluminum alloy articles having physical and mechanical properties similar to those obtained for articles produced from corresponding aluminum alloy chemistries by wrought techniques.Type: GrantFiled: September 7, 2000Date of Patent: January 25, 2005Assignee: Johnson Brass & Machine Foundry, Inc.Inventors: Steven A. Clark, Balathandan S. Pillai
