Abstract

Abstract

The sintering behavior of tungsten heavy alloys with high Ni/Fe ratios was investigated. The results show that under the same sintering conditions, the sintered densities of the alloys and the growth rate of the tungsten grains increase with the increase of the Ni/Fe ratio. The tungsten heavy alloys with low Ni/Fe ratios are difficult to be densified by the circular sintering process. For the alloys with high Ni/Fe ratios, however, the circular sintering is a effective process to obtain a high density sintered and restrain the growth of tungsten grains during sintering.
