This paper concisely describes the good results gained in making foils of cemented carbides for TEM by ion milling technique in the study of micro-structure. Owing to the application of the ion milling technique, the problem to make the foil of cemented carbides made of hard and brittle compound phases has been solved, usually it is very difficult to make such foils by normal electrolytic polishing method. Thus very rich and distinct microstructures such as dislocation configuration, stacking fault...

This paper concisely describes the good results gained in making foils of cemented carbides for TEM by ion milling technique in the study of micro-structure. Owing to the application of the ion milling technique, the problem to make the foil of cemented carbides made of hard and brittle compound phases has been solved, usually it is very difficult to make such foils by normal electrolytic polishing method. Thus very rich and distinct microstructures such as dislocation configuration, stacking fault structure and distribution of the second phase, etc. in the alloys have been observed by TEM and the microstructure study in the cemented carbide field has been developed in our country.

本文简要地介绍了在研究硬质合金微观结构时,应用离子薄化技术制取供透射电子显微镜用的薄膜所获得的良好效果。由于离子薄化技术的采用,解决了用电解抛光方法难于解决的,对这一既硬又脆的复相合金制样的难题,从而用透射电镜观察到了该合金中非常丰富而清晰的微观结构,如位错组态,层错结构,以及第二相的分布等等,开展了我国硬质合金领域的微观研究。

This paper deals with a cobah-free sintered carbide for mining tools, which adopts high manganese steel as cementing phase. The working hard characteristics of high manganese steel provide a continuously hardened surface which is affected by impact and but is of high wear resistance. However the interior of the alloy still retains austenitie constructure with high toughness. Researches on mechanical properties show that the rokwell hardness and transuerse rupture strength of high manganese steel cemented...

This paper deals with a cobah-free sintered carbide for mining tools, which adopts high manganese steel as cementing phase. The working hard characteristics of high manganese steel provide a continuously hardened surface which is affected by impact and but is of high wear resistance. However the interior of the alloy still retains austenitie constructure with high toughness. Researches on mechanical properties show that the rokwell hardness and transuerse rupture strength of high manganese steel cemented carbide may meet the standard of industrial sintered carbide, arid the impact toughness can surpass it when the ratio of Mn/C in cementing phase is closely controlled.

本文研究一种采用高锰钢粘结之无钴矿用硬质合金,高锰钢可加工硬化的特性使受冲击作用之表面不断产生硬化获得高的耐磨性,内层则仍保持高韧性的奥氏体结构。力学性能研究指出:控制粘结相Mn/C比,高锰钢结硬质合金洛氏硬度和抗弯强度能达到工业矿用硬质合金标准,冲击韧性则可超过。

Martensitic transformation in the binder of a WC-Co cemented carbide was investigated by means of X-ray diffraction and transmission electron microscope. The trasformation of fcc to hcp structure in cobalt phase increased with increasing aging time at 750℃. The transformation process was accelerated by fluctuating compressive loading. The morphology of martensitic plates induced by stress was alternated by aging before transformation.
