The effect of quench transfer time on microstructure and localized corrosion behavior of 7050‐T6 Al alloy

The microstructure and localized corrosion behavior of the 7050‐T6 Al alloys treated with different quench transfer time were investigated. Optical microscope observations show that the volume fraction of the recrystallized grains increases slightly with prolonging quench transfer time. Scanning electron microscope observations reveal that the stable η (MgZn 2 ) phase nucleates and precipitates on grain boundaries in the process of transferring...
