Patent number: 11814713Abstract: Described herein are methods of processing heat treatable aluminum alloys using an accelerated aging step, along with aluminum alloy products prepared according to the methods. The methods of processing the heat treatable alloys described herein provide a more efficient method for producing aluminum alloy products having the desired strength and formability properties. For example, conventional methods of processing alloys can require 24 hours of aging. The methods described herein, however, substantially reduce the aging time, often requiring eight hours or less of aging time.Type: GrantFiled: November 11, 2019Date of Patent: November 14, 2023Assignee: Novelis Inc.Inventors: Cedric Wu, Rajeev G.

Publication number: 20230183841Abstract: Provided herein are aluminum alloys and methods of making these alloys. The aluminum alloys described herein are produced with a high content of recycled scrap. The recycled scrap may include used beverage can scrap and mixed alloy scrap (e.g., automotive scrap containing one or more of 5xxx, 6xxx, and/or 7xxx series aluminum alloys). Surprisingly, aluminum alloy products produced from the aluminum alloys including a high content of recycled scrap as described herein exhibit mechanical properties comparable to those displayed by high-performance aluminum alloy products, such as high tensile strength, good formability without cracking and/or fracture, and/or high elongation before fracture.Type: ApplicationFiled: April 14, 2021Publication date: June 15, 2023Applicant: Novelis Inc.Inventors: Milan Felberbaum, Guillaume Florey, Debdutta Roy, Rajeev G.

Patent number: 11649529Abstract: Disclosed are aluminum alloy products and methods of making and processing such products. Thus, disclosed are aluminum alloy products exhibiting controllable surface properties, including excellent bond durability, low contact resistance, and corrosion resistance. Aluminum alloy products described herein include a migrant element, a subsurface portion having a concentration of the migrant element, and a bulk portion having a concentration of the migrant element. The aluminum alloy product comprises an enrichment ratio of 4.0 or less, wherein the enrichment ratio is a ratio of the migrant element concentration in the subsurface portion to the concentration in the bulk portion. Additionally, the aluminum alloy products surface and/or subsurface can contain phosphorus (e.g., elemental phosphorus or oxidized phosphorus). The phosphorus containing surface provides reduced electronic stress on an electrode tip of a resistance spot welding apparatus, and an extended service lifetime (e.g.Type: GrantFiled: October 23, 2018Date of Patent: May 16, 2023Assignee: NOVELIS INC.Inventors: Liangliang Li, Theresa Elizabeth MacFarlane, Sazol Kumar Das, Peter Lloyd Redmond, Changook Son, Dewei Zhu, Yudie Yuan, Luis Fanor Vega, Milan Felberbaum, Julio Malpica, Brian Paradis, Alp Manavbasi, Dechao Lin

Publication number: 20230099830Abstract: Described are aluminum alloy products that generally have a microstructure and composition that resists corrosion. This corrosion resistance, in turn, allows the aluminum alloy products to exhibit favorable bond durability performance, such as when adhesively bonded to another product. The corrosion resistance can be achieved by controlling the composition of the aluminum alloy, including the presence and/or concentration of certain intermetallic particles, such as ?-phase intermetallic particles and ?-phase intermetallic particles.Type: ApplicationFiled: February 18, 2021Publication date: March 30, 2023Applicant: Novelis Inc.Inventors: Theresa Elizabeth MacFarlane, Lasitha Cumaranatunge, Sazol Kumar Das, Yudie Yuan, Thomas J.

Publication number: 20200010941Abstract: Described are metal products having spatially non-uniform strength and formability profiles. The spatial non-uniformity of these properties may be achieved by heat-treating the metal product in a spatially non-uniform fashion, such that different portions of the metal product exhibit different strength and formability characteristics. The metal products may be formed into stamped products, with strength and formability characteristics customized to allow for suitable drawing during the stamping process.Type: ApplicationFiled: July 5, 2019Publication date: January 9, 2020Applicant: Novelis Inc.Inventors: Peter Lloyd Redmond, Rajeev G.
