研究了少量添加金属Cr、Mo、Ta及其碳化物的WC-10％Ni合金的磁性和粘绪相的关系,探讨了在何种粘结相成分下能得到非强磁性合金。其结果表明,由于粘结相中Cr和W同时大量固溶,不管合金碳含量如何,均形成非强磁性,另外,添加Mo(Mo_2C)、Ta(TaC)的合金与纯WC-Ni合金的机构大致相同,只有在减少碳含量,增加粘结相中W固溶量的条件下才能变为非强磁性。也证明了添加Cr(Cr_3C_2)的合金的室温强度在本质上比纯WC-Ni合金低。
The relationship between magnetism and viscous phase in a small amount of WC-10% Ni alloy with addition of metals Cr, Mo, Ta and their carbides was investigated. It was explored in what binder phase composition the non-ferromagnetic alloys were obtained. The results show that non-ferromagnetism is formed due to the large amount of Cr and W dissolved in the binder phase, regardless of the carbon content of the alloy. In addition, the addition of Mo (Mo 2 C), Ta (TaC) alloy and pure WC-Ni alloy The mechanism is roughly the same, and only becomes non-ferromagnetic under the conditions of reducing the carbon content and increasing the amount of W dissolved in the binder phase. It is also proved that the room temperature strength of Cr (Cr_3C_2) -added alloy is lower than that of pure WC-Ni alloy.
