Abstract

The influence of the conditions of original components mixing and sintering temperatures on the peculiarities of microstructure formation of the cemented carbide WC + 20 mass% Ni prepared of ultra-coarse-grained (80/40 μm) tungsten carbide particles is investigated. The metallographic analysis shows that for the formation of such hard alloy microstructure, it is sufficient to use liquid phase sintering and preliminary economical wet mixing of WC with Ni powder. The strength under bending and compression is 1530 and 1720 MPa, respectively, the density is 13.51 g/cm3, and the hardness is 76 HRA. For the first time, the compressive stress-compression strain curve for this alloy with an average carbide grain size of 20 μm is experimentally obtained. The alloy plasticity is 6 times higher than that of the alloys prepared under other technological modes.

具有超粗粒度微观结构的硬质合金 WC + 20 质量% Ni 的制备方法和性能特征
研究了原始成分混合条件和烧结温度对由超粗粒(80/40 μm)碳化钨颗粒制备的硬质合金 WC + 20 质量% Ni 的微观结构形成的特殊性的影响。金相分析表明,要形成这种坚硬的合金微观结构,只需采用液相烧结和初步经济的湿法混合碳化钨和镍粉。弯曲和压缩强度分别为 1530 和 1720 MPa,密度为 13.51 g/cm3,硬度为 76 HRA。首次通过实验获得了这种平均碳化物晶粒尺寸为 20 μm 的合金的压缩应力-压缩应变曲线。该合金的塑性比其他技术模式下制备的合金高 6 倍。
