Influence of Natural Aging Time on Two-Step Aging Behavior of Al-Mg-Si(-Cu) Alloys
Nanoclusters formed during natural aging cause the negative effect of the two-step aging in the age-hardenable Al-Mg-Si alloys. The relationship between the clustering behavior during natural aging and the two-step aging behavior was studied using the hardness, differential scanning calorimetry (DSC), electrical resistivity measurements, transmission electron microscopy (TEM) observation in the...
متن کاملATOM PROBE CHARACTERIZATION OF PREPRECIPITATE CLUSTERS AND PRECIPITATES IN Al-Mg-Si(-Cu) ALLOYS
Pre-precipitation clustering and chemical nature of the metastable precipitates in aged Al-Mg-Si(-Cu) alloys have been investigated by atom probe field ion microscopy (APFIM) and transmission electron microscopy (TEM) for better understanding of the two-step aging behavior and the effect of excess Si. After a prolonged natural aging, co-clusters of Mg and Si atoms are observed in addition to se...

متن کاملFluidized Bed Heat Treatment of Cast Al-Si-Cu-Mg Alloys
The effects of fluidized bed heat treatment on the microstructural and mechanical properties of Al-Si-Cu-Mg cast alloys, namely,3 54 and 319, were studied. The heating rate in fluidized beds (FBs) is greater vis-a`-vis conventional electrical resistancef urnaces (CFs). The high heating ratei nF Bs increases the kinetics of metallurgical phenomena such as Si fragmentation and spherodization duri...
