The effect of a load on the microstructure of 2124 aluminum alloy was investigated by employing transmission electron microscopy. When the alloy was aged at 190°C under a load of 6.05 kg, the deformation was increased with the aging time prolonging. Meanwhile the length of Al 2 CuMg(S) phase was shorter than the length of S phase in the alloy without loading. At the same time, there was no preferential orientation effect on S phase or Genier Preston Bagaryatsky (GPB) zones.
