| 摘 要： | 本文简单介绍自制的1.5千瓦电子束浮区区熔装置及其工作情况。应用这种装置我们制备了直径4毫米、长2—5厘米的钼单晶体,并掌握了制备定向单晶体的实验技术。制备的钼单晶体没有择优取向;显微镜观察发现晶体表面有大量的台阶(高度在2.3×10-5—6.3×10-4厘米),初步推断为蒸发台阶。

| Abstract: | An electron bombardment furnace for laboratory use for the production of refractory metal single crystals is described. Molybdenum single crystals have been prepared and examined. Technique for the production of single crystals with controlled orientation is described. Microscopic examinations disclosed numerous terraces on the surfaces of Mo crystals, these terraces were tentatively identified as evaporation terraces. |
