Self-compacting high density tungsten-bronze composites
(Elsevier, 2013-07)
Green compacts of W–bronze were encapsulated in shells of bronze powder, placed in a ceramic mold and sintered in alumina tube furnace at 1150 °C. Throughout the sintering cooling stage the differential coefficient of ...
The role of the activator rich-W interboundary layer on liquid phase sintering of W-pre-alloy bronze composites of Fe and Co additions
(Elsevier B.V., 2012-11)
In this study, the effects of 1-3 wt.% Fe and Co additions on the sintering of W 40-80wt.%-pre-alloy bronze Sn 10 wt.%-Cu compacts were examined. The isothermal part of the sintering process was conducted at temperatures ...
The factors affecting the swelling of W–bronze composite system at different sintering conditions
(Scientific.Net, 2012-12)
During sintering of Wbronze metal matrix composites, the difference in the interdiffusuion path, sintering atmosphere and alloying element might be the source of the swelling phenomenon. In this study, the factors lead to ...
