摘　　要：通过对YT14（WC－TiC－Co合金）、YG15（WC－Co合金）两种合金热处理前后其粘结相、硬质相、应力状态等方面的分析研究，结果发现，合金热处理后，粘结相中Co含量增加，马氏体相变得到抑制，碳化钨晶粒邻接度下降，同时，还改变了合金内部的应力状态。作者从多方面阐述了热处理的强化作用。The binding phase, the hard phase, the stress state before and after heat treatment of two kinds of alloy: YT14(WC-TiC-Co)and YG 15 (WC - Co ) were analysed and studied. It was found that after heat treatment increase in Watom conten and to be restrained of the martensitic phase in the binding phase,decrease of the adjacency of WC grain as ngingstress stste inside the allogs. Yhe authors expounded in many ways the effect of strengthening of heat trearn
