Trans. Nonferrous Met. Soc. China 28(2018) 2401-2409 Flow stress and dynamic recrystallization behavior of Al-9Mg-1.1Li-0.5Mn alloy during hot compression process Xi-hong CHEN1,2, Cai-he FAN1, Ze-yi... with decreasing deformation temperature and increasing strain rate. Conversely, the high angle grain boundary area increases, the grain boundary is in serrated shape and the dynamic recrystallization......
. In the lower strain rate range (10-3-10-1 s-1), the alloy exhibits stress peak in the initial stage and gradually softens subsequently until steady-flow. The primary mechanism of Ti2448 alloy at lower strain rate is discontinuous dynamic recrystallization (DDRX), with the characteristic of nucleation and new grain growth. In the higher strain rate range of 1~63 s-1, the alloy presents obvious hardening......
Multilayer Graphene:A Potential Anti-oxidation Barrier in Simulated Primary WaterHongliang Ming,Jianqiu Wang,Zhiming Zhang,Siyan Wang,En-Hou Han,Wei KeKey Laboratory of Nuclear Materials and Safety... oxidation was studied in simulated primary water of pressurized water reactors(PWRs).
