Analysis of AlSi9Mg alloy crystallization with use of ATND method

The paper discusses crystallization research aluminum-silicon casting alloy (AlSi9Mg) with use of Thermal-Voltage-Derivative Analysis method (ATND). Method of analysis of non-ferrous metals crystallization assures comprehensive image of formed structural components of the alloy. Below are shown results of crystallization analysis of ATND method in graphic form (crystallization diagrams). In the crystallization diagrams of the AlSi9Mg alloy are presented thermal and voltage curves with their derivative. Individual structural constituents crystallizable in the investigated alloy are reflected on curves of the method in form of characteristic peaks. Moreover, the paper presents structures of the investigated alloy together with marked structural constituents which were identified with use of X-ray microanalysis.
