Patent number: 11643713Abstract: A spinodal copper-nickel-tin alloy with a combination of improved impact strength, yield strength, and ductility is disclosed. The alloy is formed by process treatment steps including solution annealing, cold working and spinodal hardening. These include such processes as a first heat treatment/homogenization step followed by hot working, solution annealing, cold working, and a second heat treatment/spinodally hardening step. The spinodal alloys so produced are useful for applications demanding enhanced strength and ductility such as for pipes and tubes used in the oil and gas industry.Type: GrantFiled: October 20, 2020Date of Patent: May 9, 2023Assignee: Materion CorporationInventors: W.
