An investigation of lanthanum oxide(La_(2)O_(3))addition to tungsten heavy alloy(WHA)with a ternary composition of W-7 Ni-3 Fe was reported in this study.The mixed powders were sintered using spark plasma sintering(SP...
The aim of this research was to examine the effect of microstructural parameters on the tensile properties of different compositions of tungsten heavy alloys. The microstructural parameters (grain size, connectivity,...
A new tungsten heavy alloy, W-Ni-Fe-TiB_2 was studied. This ally has higher hardness than tradition-al tungsten heavy alloy. Sintering time was 30 min for producing the alloy. In the new tungsten heavy alloy, four pha...
