In this paper, an investigation was made of the wettability of titanium and tungsten carbides and also of (Ti, W)C solid solutions by the molten intermetallic compound Ni/sub 3/Al, which has been used for some time as a binder for sintered carbides.Abstract:
In this work an investigation was made of the wettability of titanium and tungsten carbides and also of (Ti, W)C solid solutions by the molten intermetallic compound Ni/sub 3/Al, which has been used for some time as a binder for sintered carbides. The wetting process was investigated using the stationary variation of the sessile drop method in vacuum on a special induction unit with an Alundum tube enveloping a graphite fabric one, which serves as the heating body. The carbide-intermetallide contact zone was investigated by optical microscopy and micro-x-ray spectral analysis. The investigations conducted showed the possibility in principle of creation of compact TiC-WC pseudobinary system carbide-Ni/sub 3/Al intermetallide composites produced by liquid-phase sintering. Diagrams and table are included.read more

Wear mechanisms of WC–10Ni3Al carbide tool in dry turning of Ti6Al4V
TL;DR: In this article, the possible beneficial effect of Ni 3 Al binder on WC-based cemented carbides in dry machining of a titanium alloy was studied, and the results showed that WC-10Ni 3 Al has better cutting performance than WC-8Co, especially at the higher cutting speed of v c ǫ = 100 m/min.
