The effects of small amount (up to 3%) of additional Cr, Mo, Ta or their carbides on the magnetism of WC-10%Ni cemented carbide were studied in relation to the binder phase composition to describe the state in which the alloy became non-magnetic.

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 deforamation characteristics of WC-(10~30)%Co cemented carbide were studied in the temperature range from room-temperature to 1000℃ by means of three-point bend test as a function of cobalt contents, carbide grain size and domain size of binder.It was found that, in the alloy with a fixed cobalt content, the deformation became suppressed above about 800℃ with increasing carbide grain size and above about 600℃ with increasing domain size of binder, effects of the two factors being in quite inverse to...

The deforamation characteristics of WC-(10~30)%Co cemented carbide were studied in the temperature range from room-temperature to 1000℃ by means of three-point bend test as a function of cobalt contents, carbide grain size and domain size of binder.It was found that, in the alloy with a fixed cobalt content, the deformation became suppressed above about 800℃ with increasing carbide grain size and above about 600℃ with increasing domain size of binder, effects of the two factors being in quite inverse to those observed at lower temperatures. It was also found that at a fixed temperature the transverse-rupture strength of the alloy generally increased with the steepness of load-deflection curves.

用三点弯曲试验,研究了室温~1000℃下Co含量、碳化物粒度和粘结相粒度等因素对WC-(10~30)%Co硬质合金变形特性的影响。实验结果表明:Co含量一定时,约在800℃以上碳化物粒度越粗的合金,约在600℃以上粘结相粒度越粗的合金,越难以变形。在分别低于上述温度时这些现象相反。还表明,在一定温度下,载荷-挠度曲线越陡,合金的抗弯强度一般也越高。

It is important in practice to select an efficient tool material to machine elements made of hardened steel. A series of experiments on cutting performances, including wear and fracture of the composite ceramic tool developed by our Institute and some of newly developed cemented carbides at home were made. The opitimal tool geometry of different tool materials and empirical formula of wear of ceramic tool have been proposed. Experiments have shown that tool life by wear of ceramic tool is far greater than the cemented carbides so far developed, especially in the range of high cutting speed. It is believed that our ceramic tool is more efficient and may be used in fine and finish turning hardened steels.Its tool life by fracture in interrupted operation, however, is much less than the later and could only be used in finish turning hardened steels with smaller cutting area. All these experiments indicate that the method presented for testing cutting performane with the curve of tool life by fracture may be used to evaluate the cutting abiliiy of new tool materials in interrupted conditions, because of its simplicity and reliability.

生产中有许多淬硬纲件需要切削加工。本文系统试验研究了我院研制成功的组合陶瓷刀和国内几种新牌号硬质合金加工淬硬纲的切削性能,包括磨损寿命和破损寿命。通过研究提出了它们的合理几何形状,和陶瓷刀的磨损量与切削用量之间关系式,可供推广使用参考。陶瓷刀磨损寿命比新刀片高很多倍,特别在高切削速度范围更突出。它适于精车和半精车淬硬纲。断切时,陶瓷刀的破损寿命与新刀片相比,差距较大,只适于小切削截面的精车。通过试验表明,本文用破损寿命曲线试验刀具材料切削性能的方法,比较简单可靠,可作为评定新刀具材料切削性能之用。
