Effects of heat treatment process on stress corrosion cracking and microstructures of 7A05 Al alloy plate CAI Gang-yi(蔡刚毅), L? Guang-shu(吕广庶), MA Zhuang(马 壮) School of Materials Science and Engineering, Beijing Institute of Technology, Beijing 100081, China Received 28 July 2006; accepted 15 September 2006 Abstract: In order to improve the stress corrosion cracking(SCC) resistance of 7A05Al......
. The calculated value of stress exponent, n=6.3, suggests that the compressive creep behavior of the ageing-treated Mg-5%Sn alloy is controlled by dislocation creep at the temperature of 473 K and the stresses from 25 MPa to 35 MPa. Key words: Mg alloy; aging treatment; creep deformation; stress exponent  ......

However, the changes in G* and δ of OMMT modified bitumen are small before and after PAV. Compared with the pristine bitumen, OMMT modified bitumen presents......
see that with increasing aging time, the stress rupture life decreases, namely the longer the aging time, the shorter the stress rupture life. It is worth mentioning that the stress rupture life decreases dramatically after isothermal aging for 1000 h, while the reduction in the stress rupture life decreases slowly as the aging time increases further. This phenomenon might be associated......
