摘    要：本文研究了wC-高锰钢钢结硬质合金中的微观组织及相结构。用金相实验观察到硬质相wc有两种几何形态;用电解萃取及X光衍射测定出合金中存在有WC、γ-Fe、M₆C、M₂₃C₆、FeNi相、并用TME观察了各相的形貌及结构,指出M₆C是本合金的主要碳化物析出相。

Abstract: This paper deals with the microconstituent and the phase structure in theWC-high manganese steel bonded hard alloy. The two kinds of geometrical morphologyof hard phase WC have been observed with optics microscope. There are WC,γ-Fe,M₆C, M₂₃C₆, and FeNi phases in the alloy which have been measured with methodsof the X-ray diffraction and physicochemical electrolysis extraction, and everyphase morphology and structure have been observed by means of transmission electronmiscroscope. Research work shows M₆C phase is the main precipitation phase inthe alloy.
