钼的延性受表面状态影响很大。为此前人已做过许多工作,比如,采用化学研磨法去除少量表面层来改善钼板的弯曲性能,掺杂碳来改善钼板的延性等。本文提出用富硼表面层亦可改善钼板的延性。对此进行了下述试验。 The ductility of molybdenum is greatly influenced by the surface state. To this end, many people have done a lot of work, for example, the use of chemical grinding method to remove a small amount of surface layer to improve the bending performance of molybdenum plate, carbon doping to improve the ductility of molybdenum plate. This paper proposes that the boron-rich surface layer can also improve the ductility of molybdenum plate. The following test was performed on this.
