Description
The aim of this study was to investigate the effect of swaging on the microstructure and mechanical properties of vacuum sintered 90W-7Ni-3Fe alloys. Cold isostatically pressed samples were sintered under vacuum at 1510 degrees C, for 30 min. Samples were then 15% cold rotary swaged. The study has shown that, mechanical properties of relatively low density (<98% theoretical) liquid phase sintered 90W-7Ni-3Fe alloy can be considerably improved by swaging due to increase in density and strain hardening.
