Aging Response and Elevated Temperature Strengthening in Brazing Sheet Core Alloys of 3xxx Series Aluminum 2001-01-1725
In this study, the age hardening effect in different braze sheet core alloys with varying levels of Mg was evaluated through tensile tests performed at their respective aging temperatures. The investigated temperature range was room temperature to 250°C.
As the Mg content of the material increased, the extent of age hardening increased and the gain in yield strength was retained up to a higher temperature. For the material with 0.5 Mg, the yield strength at 175°C following peak aging at 175°C was about 60 % greater than the as-brazed yield strength. While the overaging did not occur after 2500 hours of aging at 104°C, the yield strength of material with 0.5 Mg following aging for 1500 hours at 175°C was higher than its as-brazed yield strength.
