| 摘 要： | 1 IntroductionTo improve the durability of Ti(C, N)-basedcermet, many scholars have gained some measures, for example, using advanced sintering methods, Processing HIP blot isostatic pressing)trCdrieflt. Later in 1990's, there are a few reports on submicron cermets 1, 2].In this Study, we have characterized themicroS~ture of tWo cermets and interpretedthe difference between them.

| Abstract: | The influence of raw powder particle size on the properties and microstructures of Ti (C, N)-based cermets has been studied. The conclusions are as follows: The microsmictures of cermets were composed of two kinds of grains, the one with black cores surrounded by obvious rim structures, and the other whose cores were white with unconspicuous rim structures and adhesive phase. In the cermet made from fine powders, the amount of grains with white cores was much more than that in cermet made from coarse powders. In addition, their properties were also much better. |
