提高合金耐热强度的途徑之一是提高固溶体的原子鍵强度。研究各种元素对合金原子鍵强度的影响,可以指导我們建立适用的合金系統。本文在于研究鎢和钼对于鉄的原子鍵强度的影响,由于钼的作用已研究得比較細致,所以着重研究Fe-W以及Fe-W-Mo,从而比較鎢与钼的作用。为了能更精确的表征原子鍵强度,我們企图利用多种方法,包括切变模量与內耗,德拜溫度及扩散系数。并且利用結構分析及物理性質来判断合金元素溶解的情况。
One of the ways to improve the heat resistance of the alloy is to increase the atomic bond strength of the solid solution. Studying the influence of various elements on the atomic bond strength of the alloy can guide us to establish a suitable alloy system. This article focuses on the effects of tungsten and molybdenum on the atomic bond strength of guaiacolides. Since the effect of molybdenum has been studied more carefully, we focused on the effects of tungsten and molybdenum on Fe-W and Fe-W-Mo. In order to more accurately characterize the atomic bond strength, we have attempted to utilize a variety of methods, including shear modulus and internal friction, Debye temperature and diffusion coefficient. And the use of structural analysis and physical properties to determine the dissolution of alloy elements.
