Infiltration Behavior Of Mechanical Alloyed 75 wt% Cu-25 wt% WC Powders Into Porous WC Compacts

INFILTRATION BEHAVIOR OF MECHANICAL ALLOYED 75 wt% Cu-25 wt% WC POWDERS INTO POROUS WC COMPACTS PROCES INFILTRACJI POROWATYCH KSZTAŁTEK WC Z WYKORZYSTANIEM PROSZKU 75% Cu-25 WC WYTWORZONEGO METODĄ MECHANICZNEGO STOPOWANIA

In this work infiltration behavior of mechanical alloyed 75 wt% Cu – 25 wt% WC powders into porous WC compacts were studied. Owing to their ductile nature, initial Cu powders were directly added to mechanical alloying batch. On the other hand initial WC powders were high energy milled prior to mechanical alloying. Contact infiltration method was selected for densification and compacts prepared ...

Mechanical properties of hot-pressed Al-4.5 wt. % Cu/WC composite

In this study, the elemental powders of aluminum and copper were initially subjected to mechanical alloying using an attrition ball mill under argon atmosphere to produce an Al-4.5 wt% Cu powder alloy. The WC nanoparticles were then added to the powder alloy and milled in a planetary ball mill to explore the role of the WC nanoparticles on the mechanical properties of the fabricated composite p...

Aqueous Processing of WC-Co Powders

PREPARATION AND SINTERING OF W-20%Wt Cu COMPOSITE POWDERS PRODUCED BY CO-PRECIPITATION METHOD

Abstract: materials can be fabricated by sintering of W-Cu composite powders. In this research W-20%wt Cu composite powderswas synthesized via a co-precipitation method. Precipitate obtained from a mixture of copper nitrate and ammoniumparatungstate (APT) in distilled water contained W-Cu compounds. This precipitate was washed, dried and calcinedat 550 of dried precipitate powder was determined...
