Structure and mechanical properties of formed tungsten based materials

Abstract

High-melting metals belong to transitional metals that are characterised by strong atomic bond in crystal lattice and thus by high-melting temperatures, high strength and heat resistance. These metals considerably surpass other metallic structural materials by their absolute strength level and relative strength (ratio of ultimate strength to density). High corrosion resistance in concentrated acids and some physical properties of high-melting metals, such as high electric resistance, high electron emissivity, etc. also belong to their sought-after properties.
