Severe distortion is one of the four core effects in single phase high entropy alloys (HEAs) and contributes significantly to the yield strength. However, the connection between the atomic scale lattice distortion and macro scale mechanical properties thro ugh experimental verifications has yet to be fully achieved, owing to two critical challenges: (1) the difficulty in the development of homogeneous single phase solid solution HEAs and (2) the ambiguity in describing the lattice distortion and related meas urements and calculations. We have developed the single
Recently, exceptional properties that are continuously found in an intriguing new class of metallic structural materials, high entropy alloy s (HEAs), demonstrate their great potential for engineering applications particularly in extreme environments where conventional alloys reach their limits. The concept of HEAs has revolutionized traditional alloy design in particular i n terms of their endl ess composition space, which meanwhile brings a new challenge of how to effectively design HEAs with targeted properties. Here we focus on the design of advanced precipitate
The serrated flow, which is characterized by fluctuations in the stress strain curve, is associated with plastic deformation that can degrad e material properties. This presentation will give an overview of past and current theoretical modeling and analysis techniques used to study the serrated flow phenomenon in different alloy systems, including high entropy alloys (HEAs).
In this presentation, I will briefly highlight the research activities on bulk metallic glasses (BMG), high entropy alloys (HEAs), and other structural materials by our group members and collaborators. I am most grateful that many wonderful students and friends have greatly and graciously help and formulate our research activities. It is truly a great pleasure for me to learn from and interact with our students and friends on research, papers and proposal writings.
核电用钢材料需具备抗辐射、抗高温等性能。本研究主要用三维原子探针研究了17-4PH及T91两种钢材料在时效及辐照下的原子级微观结构变化。在17-4PH钢的热时效过程中，研究了富Cu团簇，富Nb，富Cr团簇及G-相的形成及发展，并讨论了析出相对机械性能的影响。作为英美合作项目的子项目，对比了T91钢在中子辐照及双离子辐照下的微观结构变化，讨论了离子辐照替代中子辐照的可行性。
