The Role of Grain Boundary Diffusion in the Activated Sintering of Tungsten Powder
텅스텐 활성소결에서 입계확산의 역할
Abstract
The mechanism of activated sintering of tungsten powder was discussed in terms of diffusion and segregation of activator atoms at W grain boundaries. Shrinkage behaviours of W-0.2wt.% Ni, W-0.2wt.% Cu or pure W powder compacts during sintering at low temperatures of 900~
