The paper presents results of non-ferrous metal crystallization research with use of ATND method. The research was carried out in the Faculty of Chipless Forming Technology, University of Bielsko-Biała. The new method of analysis of non-ferrous metals alloy crystallization assures complete picture of generated structural components of the alloy. Structural components defined in the tested alloy using ATND method have been verified by X-ray microanalysis, which unambiguously has confirmed their presence. Below are presented results of the crystallization analysis with ATND method in graphic form (crystallization diagrams). In crystallization diagrams of AK7 alloy there were shown curves (thermal curve with its derivative, voltage curve and its derivative). Individual structural components crystallizing in the tested alloy are reflected on curves of the method in form of characteristic peaks. The research was carried out on AK7 aluminum cast alloy. Moreover, the paper shows the structures of the tested alloy together with marked structural components, identified with use of X-ray microanalysis.
