Bauschinger effect in precipitation-strengthened aluminium alloy 2024
Materials Science and Engineering, 1987 Abstract The influence of precipitation strengthening on the Bauschinger effect of aluminium alloy 2024 has been investigated. The material was aged at 463 and 478 K for various lengths of time. Under certain aging and straining conditions, reverse flow curves with concave parts were observed.
