Abstract
⺠Upper and lower critical cooling rates were determined for 5 Al-Mg-Si alloys. ⺠Hardness values after ageing are inversely proportional to specific precipitation heat. ⺠High temperature precipitation: Mg2Si (nucleating at primary precipitates); low temperature precipitation: βⲠand Bâ². ⺠Maximum hardness achieved after ageing as long as quenching faster than critical cooling rate. ⺠Results of DSC, structural analysis and hardness testing are in high accordance.
