In the liquid phase sintering of Tungsten-Iron-Nickel powder compacts, could the presence of carbon (between 0.6% and 1.5%) significantly influence the final microstructure by altering the diffusion and the precipitation of W in the Fe-Ni matrix?
Vadim Verlotski
Since tungsten has a greater affinity for carbon than iron and is in an overwhelming excess, it must completely "suck out" all the carbon from the Fe-Ni melt. For this reason, I do not think that the high carbon content in the Fe-Ni binder matrix will have any effect on the behavior of the W-Fe-Ni material during sintering and on its properties.
