1) Microwave sintering technology can also be used to prepare the W-Ni-Fe material,
when compared with conventional sintering, it has a significant advantage with the
aster heating rate and the shorter sintering cycle.
2) The microwave sintered 93W-Ni-Fe samples have significant densification shrinkage at
1300˚C ~ 1400˚C. After solid state sintering by microwave processing at 1450˚C, the
relative density of sintered samples is up to 98.6%, but there is an obvious phenomenon
of grain growth.
3) The inner structure of microwave liquid phase sintered samples is more
homogeneous at 1550˚C, and the average grain size of the nearly spherical tungsten is about
15 μm, the relative density of the sample sintered can reach 99%.
