Heat Treating of Other Nonferrous Alloys
Cobalt is used as an alloying element in alloys for various applications. This article provides a detailed account of the metallurgy of cobalt-base alloys. It focuses on the compositions, properties, and applications of cobalt-base alloys, which include wear-resistant cobalt alloys, heat-resistant cobalt alloys, and cobalt-base corrosion-resistant alloys. The article also describes the heat treatments such as annealing and aging, for these alloys.
This article discusses the various heat treating processes, namely, solid-solution hardening, solution treating, solution aging and dispersion hardening, for low-melting-point alloys such as lead alloys, tin-rich alloys, and zinc alloys. Heat treating of tin-rich alloys has been practiced for bearing alloys, pewterware, and organ pipe alloys. The article reviews the principles underlying these applications.
