Conclusions
A study was made of the structural changes taking place in W - Ni - Fe alloys during slow cooling from the sintering temperature. It is shown that aging occurs in the binder phase and in a layer of the refractory tungsten-base phase adjoining the low-melting-point constituent.
A W - Ni - Fe alloy sintered in the presence of a liquid phase and slowly cooled from the sintering temperature has a complex multiphase structure of a dispersed-aggregate type. The results of the present investigation provide a foundation for subsequent research into the behavior of the phase constituents of these alloys during plastic deformation and into the nature of their strength.
