| description | Aluminum alloys are still very useful materials for diverse application. The die-casting process of Al alloys is the most common technology to manufacture cast components. Therefore, the research on aluminum alloy solidification with high thermal conductivity has an important engineering significance and application value. Therefore, the purpose of this study was to determine the effect of a strontium addition on crystallization kinetics, the microstructure (including β—phase morphology) and properties of an Al-Si-Cu alloy after solidification and after precipitation hardening. In order to determine the effect of strontium on crystallization kinetics, thermal-derivative analysis (TDA) was performed. Microstructure observation, EDS chemical composition analysis and X-ray phase analysis were performed. Strontium changed the derivative curve of solidifying Al-Si-Cu alloys. After its addition, the morphology of the α + β eutectic was modified from lamellar to fibrous. |
