Research Interests:

Topic 1: Multiscale Characterization of Yielding, Hardening and Plastic Instability of Alloy Sheets under Complex Loading Paths

Funded Projects:
1) Research on geometry and grain size effects on sheet metal yielding and hardening behaviors and validity of yield criteria, National Science Foundation of China (No. **), 1 Jan, 2017 to 31 Dec, 2019.
2) Development and establishment of biaxial loading system for the characterization of material yielding behavior, the Research Grant of Beihang University, Sep 01, 2016 to Dec 31, 2018.

Project Description:
With the ubiquitous trend of product miniaturization and rapid development of microforming technology, a demand for the precision description of multi-scale deformation behavior of sheet metal increases urgently. Due to the size effect with miniaturization, the material yielding behavior and hardening law may be different under multi-scale, meanwhile, the knowledge of macroscopic plastic deformation can not be completely applicable to micro-scaled plastic forming process. In addition, the multi-scale yielding and hardening behaviors and the validity of existing yield criteria and hardening models have not yet been systematically explored and studied, which would cripple the wide applications of microforming technology in production of microparts. In this research, the yielding behavior and hardening law of sheet metal in multi-scale plastic deformation process will be systematically explored and how different geometry and grain size effects, material microstructure evolution affect them will be also extensively explored via multiaxial loading experiment and finite element method. The validity of yield criteria and hardening models, which are widely used in macro-scale forming, will be evaluated under different workpiece geometry and grain size scenarios. By employing the outcome of size affected yielding and hardening characteristics, the yield criterion and hardening model, which are suitable for describing micro-scaled plastic deformation of sheet metal will be established.

Topic 2: Microscale Plastic Deformation Theory and Precise Control of Shape & Performance for Medical Devices

Funded Projects:
Beijing Municipal Natural Science Foundation, Basic research on superplastic microforming technology of biodegradable Zinc alloy vascular stent (No. **), 2017/01-2019/12.

Topic 3: Synergetic Manufacturing Technology of Heat Exchanger for Hypersonic Pre-cooling Engine

Funded Projects:
1) Research on new method and theoretical foundation of special energy fields assisted microforming, National Science Foundation of China (No. **), 1 Jan, 2017 to 31 Dec, 2021.
2) Research on pulsed current assisted microforming of superalloy thin-walled capillary, “Double Hundred” Project of National Defense Science and Technology Bureau, 1 Jan, 2019 to 31 Dec, 2020.

Project Description:
Due to the extreme service environment of high-temperature, high-speed and high-pressure, the requirements for the dimensional accuracy, uniformity of wall thickness and comprehensive mechanical properties of the capillary tubes are vitally strict. The current multi-pass drawing process can not accurately control the geometric dimension and microstructure property, and thus the product quality can not be guaranteed. This project is aimed at realizing the batch and precision manufacturing of capillary tubes, carrying out the research of new theory and new technology of microforming assisted by the excitation of special energy fields. The influence of size effect and external exciting field on the deformation behavior of high-temperature alloy and its forming quality will be extensively investigated. Furthermore, the process route and forming parameter configuration will be determined and optimized. Based on process analysis and finite element simulation, the coupled effects of physical fields and scale effect on process configuration, defect formability and microstructure evaluation will be determined. Through the case study, the precision, batch and controllable manufacturing of superalloy thin-walled capillary will be achieved.
