摘要
70年代末我所建立了国内第一台电子旋转盘制粉炉。本文介绍利用该装置制取高温合金粉末的原理、过程和技术参数。通过电镜观察到粉末颗粒具有粗大树枝晶和等轴晶组织,枝晶的形貌、排列、尺寸随成分的不同而改变。
In the end of 70s, domestic the first set of making - power furnace of electron - beam rotating disk in China was constructed in our institute. This paper introduces the principle of making high temperature alloy powder, its procedure and technical parameters in using this device. Using electron microscope, we observde the structure of powder particle with gross dendrites and equiaxed grains. Ths topography, arrangement, size of dendrites changed with composition.
