ATOM 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 کاملPOSITION SENSITIVE ATOM PROBE STUDIES OF THE COMPOSITION OF AND ' PRECIPITATES IN Al-Cu-Mg-Ag ALLOYS
Low concentration additions of silver to Al-Cu-Mg alloys can lead to the formation of platelike precipitates, designated n , is formed on { 11 1 ] planes. Although the morphology of these precipitates has been extensively studied, little information exists about the chemistry of the n precipitates, and in particular, about local elemental segregation. In this paper we report the results obtaine...
متن کاملProperty Criteria for Automotive Al-Mg-Si Sheet Alloys
In this study, property criteria for automotive Al-Mg-Si sheet alloys are outlined and investigated in the context of commercial alloys AA6016, AA6005A, AA6063 and AA6013. The parameters crucial to predicting forming behavior were determined by tensile tests, bending tests, cross-die tests, hole-expansion tests and forming limit curve analysis in the pre-aged temper after various storage period...
متن کاملAntibacterial biodegradable Mg-Ag alloys.
The use of magnesium alloys as degradable metals for biomedical applications is a topic of ongoing research and the demand for multifunctional materials is increasing. Hence, binary Mg-Ag alloys were designed as implant materials to combine the favourable properties of magnesium with the well-known antibacterial property of silver. In this study, three Mg-Ag alloys, Mg2Ag, Mg4Ag and Mg6Ag that ...
