Effect of grain size on rotary swaging of sintered tungsten rod

Tungsten has poor processing performance and its brittleness often leads to defects. The effect of grain size on rotary swaging of the sintered rod was investigated to improve the quality of the destination part. Three different grain sizes of sintered rods were selected to research the physical and...
