Comparative Study of Creep and Stress Relaxation Behavior for 7055 Aluminum Alloy Lihua Zhan1, a, Yanguang Li1,b, Minghui Huang1,c , Jianguo Lin2,d 1 School of Mechanical and Electrical Engineering, Central South University, Changsha, China 2 Department of Mechanical Engineering, Imperial College London, UK ayjs-cast@mail.csu.edu.cn, bliyanguang131@126.com, cMeeh@mail.csu.edu.cn, dJianguo.Lin@imperial.ac.uk Keywords: 7xxx aluminum alloy; age forming; creep; stress relaxation Abstract.
Therefore a new forming technique is a key for 7xxx aluminum alloys to be used to manufacture complex-shaped panel parts.
Then a multi-step fitting process using the experimental data from creep ageing tests was used to obtain the material constants, detailed introduction was shown in Ref. [11, 12].

Therefore, separation and recovery of individual elements or groups of REs from major sources (mineral monazite, xenotime, and bastnasite) and other secondary sources (residues from processing activities, waste rock, sludges and scrap material) has to be both economically and environmentally significant, to accommodate the critical demand in a rapidly growing and developing world.
The key objectives of the present study were to separate these metal ions and determine the effects of D2EHPA concentration on the extraction efficiency of the elements.
