Improving the strength and SCC resistance of an Al-5Mg-3Zn alloy with low-angle grain boundary structure被引量：1
《Journal of Materials Science & Technology》2023年第30期63-73,共11页Z.C.Tang W.Xu D.Y.Zhao B.Zhang 
This research was financially supported by the National Nat-ural Science Foundation of China(Grant No.52171088);the Young Elite Scientists Sponsorship Program by CAST(grant No.2022QNRC001).We thank X.Si for assistance in sample prepara-tion.
The strength of traditional Al-Mg alloys is relatively low because it mainly relies on solid solution strengthening.Adding a third component to form precipitation can improve their strength,but it usually leads to hig...

δ′ Phase Precipitation at Low-angle Grain Boundary in Al-Li-Zn-Zr Alloy
《Journal of Materials Science & Technology》1990年第4期263-267,共5页蒋晓军 姚大平 李依依 
A large number of δ particles precipitated at low-angle grain boundaries have been observed by TEM in a dilute A1-Li-Zn-Zr alloy during ageing at the suitable temperatures.An explanation for this phenomenon was propo...
