【摘要】:高通量实验方法作为现代材料学研究的一种重要手段,在相图计算、金属材料的成分—结构—性能相关性等研究方向均扮演越来越重要的角色。本研究利用一种新型的连续温度梯度热处理方法制备了具有梯度显微组织的Ti5553合金,并利用SEM和TEM等检测手段对其微观组织进行表征,确定该合金的伪调幅分解的最佳温度为(617±2)℃。基于JMA方程,推导了Ti5553合金在最佳温度的动力学方程为:f=1-exp(-1.35×t~(0.91))。
[Abstract]:As an important means of modern materials research, high-throughput experimental methods play a more and more important role in phase diagram calculation and the relationship between composition, structure and properties of metal materials. In this paper, Ti5553 alloy with gradient microstructure was prepared by a new continuous temperature gradient heat treatment method, and its microstructure was characterized by SEM and TEM. The optimum temperature for pseudo-amplitude modulation decomposition of the alloy was determined to be 617 卤2 鈩,
