硬质复合材料 meaning in English

rigid composite material

In this work , using elemental powders as starting reactant materials several carbide powders such as wc , sic , tic , zrc and corresponding alloys had been fabricated by ball - milling technique . x - ray diffraction ( xrd ) , scanning electron microscopy ( sem ) , transmission electron microscopy ( tem ) and other measurement techniques had been used to monitor the structural changes of powders after some ball milling time and the properties of the cemented tungsten carbides . and the mechanism for the formation of matal carbides by ma has also been discussed
本文主要对机械合金化( ma )技术在碳化物制备中的应用进行了研究，利用高能球磨，以元素粉末为原料，制备出wc 、 sic 、 tic 、 zrc的粉体以及wc基硬质复合材料，并利用x射线衍射、扫描电镜、透射电镜等方法分析和研究了球磨过程粉体的变化以及烧结后硬质合金的性能，对机械合金化制备碳化物的有关机理进行了研究和探索。
