在这工作中,应用金相显微和电子显微的方法,研究了钼及钼合金中的多边化过程,探明了多边化形成的条件及其发展的规律性。研究结果证实了多边化对再结晶过程的抑制作用。 同时,采用测定硬度及弹性极限的方法,研究了多边化对钼及钼合金机械性能的影响;结果表明:多边形组织显著地提高了这些性能。 In this work, the application of metallographic microscopy and electron microscopy methods to study the molybdenum and molybdenum alloy in the process of multilateralism to explore the formation of the conditions and the development of regularity. The results confirm the inhibitory effect of multilateralism on the recrystallization process. At the same time, the influence of multilateralisation on the mechanical properties of molybdenum and molybdenum alloy was studied by measuring the hardness and elastic limit. The results show that polygonal structure can improve these properties remarkably.
