Abstract Scope |
The Al-Si alloying system is widely used for the most common aluminum casting alloys. However, there is strong demand for new types of casting alloys that can face increased requirements to the material performance especially in an as-casted condition. The Al-Ca alloying system has good perspectives due to the possibility of obtaining dispersed eutectic (Al) + Al4Ca in the cast state without modification and heat treatment. The investigation of Al-Ca alloys with different Ca content, as well as the influence of various alloying elements, such as Zn, Si, Fe, Mg, is necessary for the development of industrial alloys compositions. The authors investigated the effect of the content of Ca and other alloying elements on the structure, technological and strength properties of the Al-Ca alloy during high-pressure casting. It also shows the possibility of increasing the strength properties of the alloy due to the formation of ternary eutectics in the alloy. |
