FIELD-ION MICROSCOPE ATOM-PROBE ANALYSIS OF THE EFFECT OF RRA HEAT-TREATMENT ON THE MATRIX STRENGTHENING PRECIPITATES IN ALLOY AL-7150
The heat treatment of retrogression and re-ageing (RRA) has been applied to commercial alloy Al-7150 resulting in an improvement in the SCC resistance of material aged to peak strength. Transmission electron microscopy (TEM), field-ion microscopy/atom-probe (FIM/AP) analysis and position sensitive a...
