Effect of precipitation on elastic modulus of Al-Zn-Mg-Cu-Li alloys ZHAO Zhong-kui(赵中魁), ZHOU Tie-tao(周铁涛)2, LIU Pei-ying(刘培英)1, LI Huan-xi(李焕喜)1, CHEN Chang-qi(陈昌麒)1 1. School of Materials... hardening is obtained by double-ageing or multi-ageing for the Al-Zn-Mg-Cu-Li alloys. The yield strength and the elastic modulus of the Li-containing alloys have relationships with ageing processes......
; Fitting methods for relaxation modulus of viscoelastic materials DUAN Ji-an(段吉安), YANG Cheng-ling(杨成林), SHUAI Ci-jun(帅词俊) (School of Mechanical... less fitting points. These methods can fit not only experimental curve of KWW function, but also the experimental data directly. Key words: viscoelastic material; relaxation modulus; Maxwell model......
A new model to describe effect of plastic deformation on elastic modulus of aluminum alloy ZANG Shun-lai(臧顺来)1, 2, GUO Cheng(郭 成)1, WEI Gong-ji(魏公际)3, CHEN Feng(谌 峰)3, DONG Wei(董 伟)1, ZHANG Ke(张... deformation on elastic modulus is considered when the material undergoes a large plastic deformation. The present work focused on establishing a new model to accurately describe the relation of elastic......
