Effect of liquid phase on W-Ni-Sn and W-Co-Sn pseudoalloys in liquid-phase sintering

The effect of the liquid phase of different compositions on the compaction of W-Ni-Sn and W-Co-Sn pseudoalloys in liquid-phase sintering is studied. It is established that the compaction of W-Ni-Sn pseudoalloys enhances with increasing liquid-to-solid phase volume ratio. Changes in volume of W-Co-Sn pseudoalloys with a varying amount of the liquid phase in sintering depend on the melt composition: the compaction increases for 20 wt.% Co and 80 wt.% Sn and the samples grow regardless of the liquid phase amount for 50 wt.% Co and 50 wt.% Sn. __________ Translated from Poroshkovaya Metallurgiya, Vol. 46, No. 3–4 (454), pp. 3–10, 2007.
