use of the nano rare earth additive is lower than that of the ordinary rare earth additive, and the gap with the WC grain (large circle) is small, and the arrangement is more dense. The size of the ordinary rare earth additive is almost the same as that of WC, so it is easy to form a crack source. Therefore, this experiment uses nano rare earth as an additive to achieve the purpose of not improving the cost and improving the performance. China is rich in rare earth resources. If we use this kind of thinking to develop new technology, make full use of China&#8217;s tungsten ore and rare earth resources, research and develop hard alloy rare earth modified materials, improve the production level and development of China&#8217;s cemented carbide industry. High-quality and high value-added deep-processed carbide products, improving competitiveness, reversing the unfavorable situation in the international market, and achieving a virtuous cycle of raw materials are of great significance.<\/div>\n<div>2.\u7a00\u571f\u786c\u8d28\u5408\u91d1<\/div>\n<div> The rare earth element is 15 lanthanides of the third subgroup of Mendeleev&#8217;s periodic table with atomic numbers ranging from 57 to 71, plus a total of 17 elements, which are similar to those of electronic structures and chemical properties. Rare earth is known as the \u201ctreasure house\u201d of new materials, and is a group of elements that scientists at home and abroad, especially material experts, are most concerned about. Due to its special properties, rare earths have been widely used in metallurgical materials, optics, magnetism, electronics, machinery, chemicals, atomic energy, agriculture and light industry. Although rare earths are used as additives and modifiers, their direct output value and profit are not high, but the secondary economic benefits can be increased by tens or even hundreds of times. China&#8217;s rare earth resources are abundant, and its reserves rank first in the world, and its comprehensive production capacity ranks second in the world. At home and abroad, the application of rare earths and their compounds is almost everywhere in the national economy. Rare earth has obvious improvement on the performance of cemented carbide. A large number of studies have shown that the addition of rare earth can improve the strength and toughness of cemented carbide to a large extent, so that rare earth-added cemented carbide can be widely used in tool materials and mining tools. , molds, top hammers, etc., have excellent development prospects. The rare earths commonly used as additives are Ce, Y, Pr, La, Sc, Dy, Gd, Nd, Sm, and the like. The addition form is generally an oxide, a pure metal, a nitride, a hydride, a carbide, a rare earth-cobalt intermediate alloy, a carbonate, a nitrate, and the like. The type and morphology of the added rare earth affect the physical and mechanical properties of the cemented carbide.<\/div>\n<div>3\u3001\u7a00\u571f\u5f3a\u97e7\u5316\u673a\u7406<\/div>\n<div> \u786c\u8d28\u5408\u91d1\u4e2d\u5fae\u91cf\u7a00\u571f\u5143\u7d20\u7684\u52a0\u5165\uff0c\u4e0d\u4ec5\u6291\u5236\u4e86\u5408\u91d1\u5728\u70e7\u7ed3\u8fc7\u7a0b\u4e2d\u7684\u6676\u7c92\u957f\u5927\uff0c\u800c\u4e14\u63d0\u9ad8\u4e86\u5408\u91d1\u7684\u529b\u5b66\u6027\u80fd\uff0c\u4ece\u800c\u8fdb\u4e00\u6b65\u63d0\u9ad8\u4e86\u4ea7\u54c1\u7684\u4f7f\u7528\u5bff\u547d\u3002\u7a00\u571f\u5bf9\u786c\u8d28\u5408\u91d1\u7684\u5f3a\u5316\u673a\u7406\u5982\u4e0b\uff1a<\/div>\n<div>(1) \u5f20\u51e4\u6797\u7b49\u3002\u8ba4\u4e3a\u5f53\u03b3\u76f8\u4ece\u9ad8\u6e29\u51b7\u5374\u5230\u5ba4\u6e29\u65f6\uff0cfcc\u2192hcp\u662f\u4e00\u79cd\u6269\u6563\u578b\uff08\u7531Ms\u673a\u5236\u8f85\u52a9\uff09\u7684\u76f8\u53d8\u3002\u5176\u4e2d\uff0c\u03b3fcc\u548c\u03b3hcp\u76f8\u7ea6\u536010%\u3002\u7531\u4e8e\u7a00\u571f\u7684\u52a0\u5165\u53ef\u4ee5\u6291\u5236\u9a6c\u6c0f\u4f53\u76f8\u53d8\uff0c\u53ef\u4ee5\u964d\u4f4e\u7c98\u7ed3\u76f8\u4e2d\u03b3hcp\u7684\u542b\u91cf\u3002\u5176\u6291\u5236\u9a6c\u6c0f\u4f53\u76f8\u53d8\u7684\u673a\u7406\u53ef\u80fd\u6709\u4e24\u4e2a\u539f\u56e0\uff1a\u4e00\u662f\u7a00\u571f\u6c27\u5316\u7269\u9489\u624e\u4f4d\u9519\uff0c\u963b\u788d\u4e86\u4f4d\u9519\u8fd0\u52a8\uff1b\u53e6\u4e00\u65b9\u9762\uff0c\u7a00\u571f\u6c27\u5316\u7269\u88ab\u9489\u624e\u5728\u7f3a\u9677\u4f4d\u7f6e\uff0c\u4f7f\u6f5c\u5728\u7684\u03b5\u6210\u6838\u6838\u80da\u51cf\u5c11\u3002\u7531\u6b64\uff0c\u8106\u6027\u03b5\u76f8\u51cf\u5c11\uff0c\u97e7\u6027\u03b1\u76f8\u589e\u52a0\u3002<\/div>\n<div>\u738b\u745e\u5764\u7b49\u8ba4\u4e3a\uff0c\u5728\u786c\u8d28\u5408\u91d1\u4e2d\u6dfb\u52a0\u5fae\u91cf\u7a00\u571f\u53ef\u4ee5\u6291\u5236Co\u7c98\u7ed3\u76f8\u4e2d\u5c42\u9519\u7684\u6269\u5927\uff0c\u4ece\u800c\u6291\u5236fcc \u03b1-Co\u2192hcp \u03b5-Co\uff08\u5c42\u72b6\u5f62\u6838\uff09\u7684\u8f6c\u5316\uff0c\u4f7ffcc \u03b1 -
