TENSILE STRENGTH AND CREEP RESISTANCE OF Mg-9Al-1ZnBASED ALLOYS WITH CALCIUM ADDITION Y.S.Sun1,W.M.Zhang1,X.G.Min1 (1.Department of Materials Science and Engineering, Southeast University, Nanjing 210096, China) Abstract:Small amount of calcium addition to the Mg-9Al-0. 8Zn-0.2Mn(AZ91) alloy resulted in the obvious influence on mechanical properties. The yield strength of the alloys increased......
Theoretical and experimental analyses of casing collapsing strength under non-uniform loadingLIN Yuan-hua(林元华)1,2, DENG Kuan-hai(邓宽海)1, ZENG De-zhi(曾德智)1, ZHU Hong-jun(朱红钧)3, ZHU Da-jiang(朱达江)1, QI...:Failure data from oilfield showed that casings which were designed according to API standards were deformed and collapsed in salt formations. The main reason for decrease in strength may be caused by non......

Enhancement the Adhesion between Epoxy Coating and Rusted Structural Steel by Tannic Acid TreatmentYang Li,Yuantai Ma,Bin Zhang,Bing Lei,Ying LiState Key Laboratory for Corrosion and Protection..., and the adhesion of the epoxy top-coating system was evaluated. The results showed that the adhesion between the epoxy coating and the rusted steel after treatment was enhanced from 1.93 to 5.97 MPa......
Influence of yield-to-tensile strength ratio (Y/T) on failure assessment of defect-free and corroded X70 steel pipelineZHANG Shun-hu(章顺虎)1, 2, ZHAO De-wen(赵德文)1, WANG Xiao-nan(王晓南)2(1. State Key... strength ratio (Y/T) on failure pressure of X70 pipeline without and with corrosion defects was investigated. The stress-strain response of materials was characterized by a power-law hardening curve......
