Abstract
Foundry Al-Mg alloys found an important role in overall foundry industry of light metals due to their outstanding properties, although theirs solidification mechanism has not been clearly determined. Solidification overview of multicomponent technical AlMg9 alloy was obtained in this work. One of significant achievement was application of “disturbed” solidification method by quenching at exactly determined temperature to obtain frozen microstructure. This method enables correlation between characteristic temperatures of phase transformations and corresponding characteristics of microstructure constituent. Mathematical expression related to the quenching temperature and time enable prediction of microstructure evaluation during solidification of AlMg9 alloy. Chemical composition determination of particular phases, carried out by energy dispersive specter (EDS), resulted in identification of Alx(MnFe)ySiz, Mg2Si and Al8Mg5 phases. Temperature and time solidification sequence were determined and compared to the predicted ones, by phase diagram modeling. Also, the change of particular phases ratio during solidification process was established also by mathematical modeling. These models offer an oversight of the required solidification microstructure evaluation.
