Heat radiative characteristics of ultra-attenuated materialsDehong Xia and Yonghong WuMechanical Engineering School, University of Science and Technology Beijing, Beijing 100083, China摘 要:<正> From the microstructure of heat radiation, the interaction between the incident heat radiative wave and the electromag-netism syntonic wave is analyzed......
was significantly affected by two factors, namely, the Zn content and the heat treatment process. A possible formation mechanism of such growth twins was discussed using the viewpoint of vacancy. Key words: Mg-Zn-Cu-Zr alloy; Mg alloys; twinning; heat treatment; vacancy 1 Introduction Mg alloys are the lightest metallic structural materials and have many inherent advantages such as high specific strength......
