The precipitation sequence of η(MgZn2) phase along low-angle grain boundaries in Al-Zn-Mg-Cu alloy was investigated by examining samples aged at 135 ℃ for various times from 5 min to 6 h. High resolution transmiss...
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...
