Strength And Ductility

Nanostructured metals which have nano-scale microstructure are classified into ultrafine grained metals and nanocrystalline metals. In recent years, many processing techniques have been developed for producing nanostructured metals. Nanostructured metals possess ultrahigh strength but the low ductility is an important limitation on development of these materials for structural applications. This paper overviews various methods of producing nanostructured metals and recent investigations of strength and ductility of nanostructured metals processed by sever plastic deformation.

Abstract ANACONDA Alloy 360 is a leaded brass and is the alloy most often used for high-speed machining operations; it fills most of the needs for such purposes. Alloy 360 is the standard free-cutting brass and its machinability has become the standard by which all other copper-base alloys are rated. It has medium strength and ductility. Alloy 360 is used for hardware such as gears and pinions where excellent machinability is of prime importance and for all types of automatic high-speed screw-machine products. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties. It also includes information on corrosion resistance as well as forming, heat treating, machining, and joining. Filing Code: Cu-447. Producer or source: Anaconda American Brass Company.

Abstract COPPER ALLOY NOS. C44400 and C44500 are copper-zinc-tin alloys inhibited by antimony and phosphorus, respectively. They are commonly known as inhibited admiralty metal or admiralty brass. They have a good combination of strength and ductility and good resistance to general corrosion. The small addition of inhibitor is made to minimize the alloy’s susceptibility to dezincification and stress corrosion. They are used for condenser, evaporator and heat-exchanger tubes and associated applications. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties as well as fracture toughness and creep. It also includes information on corrosion resistance as well as forming, heat treating, machining, and joining. Filing Code: CU-599. Producer or source: Copper and copper alloy mills.
