| Metallic materials play an essential role in materials commonly used in many developmental industries. A characteristic feature of their crystalline structure is the ordered arrangement of the constituent physical elements in space according to the defined laws of thermodynamics and chemical reactions. Therefore, conscious control of technology to obtain the optimal structure of these materials is based, among other things, on the control of the applied methods of crystallization, modification and optimization of the smelting, casting parameters as well as possible heat treatment procedures, which guarantee the appropriate quality. The presented work discusses the crystallization process of the modified ultralight Mg-Li cast alloys based on the thermal-derivative analysis, which visually uses the effects of phase transformations occurring in metal alloys in a liquid state, accompanied by a change in energy and the release of the latent heat of crystallization. |
