Yu Qian a postgraduate of Micro-Nano-Scale Materials Behavior Research Center of the State Key Laboratory of Mechanical Behavior of Metal Materials, Xi'an Jiaotong University with the cooperation with Prof. Li Ju of Pennsylvania University of USA, Dr. Huang Xiaoxu of Raith National Laboratory of Denmark, conducted an in-depth research on twinning deformation behavior in the small-scale metal single crystal materials and its influence on the mechanical properties of the materials.
The research revealed that the dimensions of single crystal can bring significant influence onto the deformation behavior and mechanical properties of twinning crystal. The research was carried out under the guidance of Prof. Sun Jun, Prof. Xiao Lin, Prof. Ma En and Prof Shan Zhi Wei, who are in the same research center and the result has been published in Nature on January 21.
Reviewers were very impressed by the pioneering work. They said that the author has made significant progress in the research on the mechanical-dimension effect.
The research plays a very important role in systematically investigating the small-scale mechanical behavior of materials. The achievement will be of much help in the property evaluation and design for microelectronic components and micro-electromechanical systems, in particular for the micro-nano processing by means of the intensive crystal-dimension effect.
The research has receives financial support from the National Natural Science Fund "973" project, and the first batch of Innovation & Talents Projects of the State Foreign Experts Bureau / Ministry of Education, respectively
