Influence of the nano-WC content and Sintering Temperature on the Phase Composition of Hard Alloys in the System TiC–WC–VC–NiCr

Influence of the nano-WC content and Sintering Temperature on the Phase Composition of Hard Alloys in the System TiC–WC–VC–NiCr

The effect of the WC content and the sintering temperature, as the main technological factor, on the phase composition of TiC–xWC–5VC–18NiCr alloys was investigated by X-ray phase analysis. It was established that the main phases in the investigated alloys were the NaCl-type quaternary (Ti,V,W)C pha...
