Sintering of Tungsten and Tungsten Heavy Alloys of W–Ni–Fe ...
09.08.2016& 0183;& 32;In W–Ni–Fe alloy the W grains get interspersed in the FCC matrix of Ni–Fe–W solid solution. The solubility of tungsten in the binder phase increases by about 16 at% when the liquid forms. The melt spreads to fill the small pores and penetrates the grain boundaries. It also dissolves the interparticle necks resulting in the decrease of solid liquid interfacial energy below the ...
