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. 51605018), 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. 3172022), 2017/01-2019/12.

Project Description:

 

The  investigation can be subdivided into the fabrication technology of ultrafine  crystal biocompatible materials, the mechanism of low-temperature  superplastic deformation of nanocrystalline zinc alloy, the size dependent  corrosion behavior of biomaterials, the thermally assisted microforming  technology of titanium alloy micro-components, and the precise control of structure  and performance for high-performance degradable medical components.

 

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. 51635005), 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.

 

Topic 4: 3D Hydroforming Technology for Aeronautical  complex ultra-thin wall components

Funded Projects:

Research  on the accurate forming technology of metallic bellows for aviation engine, Innovation  fund, 1 Jan, 2019 to 31 Dec, 2021.

Project Description:
