Abstract (en)
The invention relates to sintered alloys containing carbide, which are used as materials for high speed steels, having - a first phase comprising hard material particles, such as tungsten carbide and/or molybdenum carbide and/or chromium carbide and/or vanadium carbide and/or niobium carbide and/or tantalum carbide and/or mixed carbides of the said metals, having a grain size of between 2 mu and 7 mu , and - a second phase comprising an iron-based alloy which surrounds the particles of the first phase and - having a density of greater than 99.9% of the theoretical density.
