Nearly full fine ferrite microstructure (d=2.7±0.5µm) and fine ferrite (d=2.4±0.3µm) plus ~8.9% retained austenite with relatively good stability were produced. The upper shelf energy increases by ~30J and the CVN impact energy increases by ~60J at −100°C by introducing ~8.9% retained austenite. The high toughness (263J at −40°C and 191J at −100°C) has been achieved by grain refinement and retained...
The effect of elastic tensile stress on the microstructure of 7075 Al alloy aged at 393–453K for 1h has been investigated in this paper. It was found that during the low temperature aging, the external stress lessens the size of the GPI zones. GPII zones are just identified in the stress-free aged condition. A new edge-on η′ platelet is observed in the stress-aged specimen. During the high temperature...
