Comparison of liquid phase sintering and Cu-melt infiltration methods to consolidate 80W-Cu composite using nickel as sintering activator
Hafed, Ibrahim; Azizan, Aziz, Assoc. Prof. Dr.; Azmi, Rahmat, Prof.; Kahtan Sadiq, Muhammed, Dr. (Trans Tech Publications, 2013)In this article, studies were conducted to evaluate the densification of W- Cu sintered compacts produced using two methods; liquid phase sintering (LPS) and combination of liquid phase sintering and liquid infiltration ... -
Effects of cobalt addition and temperature on microstructure and density of w-25Cu composites prepared via liquid infiltration
Hafed, Ibrahim; Azizan, Aziz; Azmi, Rahmat (Trans Tech Publications, 2012-12)In this study, the effect of Co and sintering temperature on microstructure of W-25Cu composites prepared via copper melt infiltration has been investigated. The concentration of Co addition used ranged from 0.5 to 3wt. ... -
Enhanced liquid-phase sintering of W–Cu composites by liquid infiltration
Hafed, Ibrahim; Azizan, Aziz; Azmi, Rahmat (Elsevier, 2014-03)Full-density of consolidated W–Cu composites produced via conventional sintering method is difficult to achieve. In this work, fully-dense W–Cu composites were developed via the combination of the liquid phase sintering ...
