Abstract

The invention discloses a WCrRuTaV refractory high-entropy hard alloy with NbCr2 as a binder and a preparation method of the WCrRuTaV refractory high-entropy hard alloy, and belongs to the technical field of hard alloy materials. Refractory metal elements W, Cr, Ru, Ta and V are adopted as raw materials, and high-entropy hard alloy powder is prepared through mechanical alloying; and the high-entropy hard alloy powder and the NbCr2 powder are evenly mixed and then subjected to spark plasma sintering, and the block hard alloy material is obtained. The NbCr2-bonded WCrRuTaV refractory high-entropy hard alloy obtained through the method has the superfine grain size and the high density, meanwhile, the hard alloy is uniform in component distribution and excellent in performance, and therefore the NbCr2-bonded WCrRuTaV refractory high-entropy hard alloy has the good application prospect.

Description

A kind of NbCr 2 Bonded WCrRuTaV cemented carbide and preparation method technical field The present invention relates to the technical field of cemented carbide materials, specifically a kind of NbCr 2 Bonded WCrRuTaV Refractory High Entropy Cemented carbide and preparation method thereof. Background technique Cemented carbide is mainly a kind of wear-resistant alloy material with higher hardness and strength, which is widely used in machinery manufacturing. In the processing industry, it is mainly used to make cutting tools, wear-resistant parts and molds. However, in recent years, with some difficult-to-machine materials The development of the material and machining industry has put forward higher requirements for the high temperature performance of cemented carbide tools under complex working conditions. beg. Refractory metals usually refer to tungsten, molybdenum, niobium, tantalum, vanadium, zirconium, etc., with refractory, good high temperature stre...
