Abstract (en)
[origin: EP0046209A1] Composition of matter composed of 33 to 80 weight per cent of a carbide material having a particle size greater than 400 mesh, and 23 to 70 weight per cent of a metallic matrix material, the carbide material which may be a cemented composite (30), being embedded in and bonded to said metallic matrix material (25) by powder metallurgical techniques of compaction and high temperature and high pressure diffusion bonding; and tools having a cemented carbide wear or cutting element (30), these tools also being formed by powder metallurgy techniques.
