Swaging of liquid phase sintered 90W–7Ni–3Fe tungsten heavy alloy

Swaging of liquid phase sintered 90W–7Ni–3Fe tungsten heavy alloy

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°C, for 30min. Samples were then 15% cold rotary swaged. The study has shown that...

Zusammenfassung: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°C, for 30min. Samples were then 15% cold rotary swaged. The study has shown that, mechanical properties of relatively low density (
