Technological properties

Name The value
Microstructure The microstructure of the alloy to be biphasic, consisting of a solid solution based on tungsten and a matrix consisting of a solid solution based on Nickel and iron.
Particularities of production of goods Details of the alloy produced by powder metallurgy method, including hydrostatic extrusion, sintering (impregnation) in the environment of hydrogen and vacuum annealing. In the process of being sintered at 1350-1500 °C in the presence of a liquid phase occurs recrystallization of the tungsten powder with the formation of nearly spherical particles, ten times greater than the particle size of initial powder.
