摘要: In this study, high-strength AA7075 alloy samples were cryogenically forged after annealing and then subjected to solution and aging treatments. The cryogenically forged 7075-T73 alloy samples displayed equiaxed fine grains associated with abundant fine precipitates in their matrix. Compared with conventional 7075-T73 alloy samples, the cryogenically forged samples exhibited an 8-12% reduction in tensile strength and an increased fatigue strength and higher corrosion resistance. The fatigue strength measured at 10 7 cycles was 225 MPa in the bare samples; the strength was increased to 250 MPa in the cryogenically forged samples. The effect of anodization on the corrosion resistance of the bare samples was improved from ( E corr ) −0.80 to −0.61 V. 其他題名: J. of Materi Eng and Perform 出版者: New York: Springer US 出版日期: 2016-03-01 出處: Journal of materials engineering and performance, 2016-03, Vol.25 (3), p.1211-1218 資源來源: EBSCOhost OmniFile Full Text Select 版權: ASM International 2016 識別號: ISSN: 1059-9495 識別號: EISSN: 1544-1024 識別號: DOI: 10.1007/s11665-016-1946-2
