Abstract

The necessity to study the solidification parameters upon modifying Al–Si alloys is shown. The solidification of cast aluminum alloys modified by rubidium with the aim of significant improvement of their mechanical properties is analyzed. For a comparison of the efficiency of treatment with rubidium, aluminum alloys are modified by a standard flux based on sodium salts. The phase transformation temperatures and the parameters that take into account the precipitation of a solid phase in the solidification range are determined.

Rub改性铸造铝合金的凝固

摘要

显示了在改性Al-Si合金时研究凝固参数的必要性。为了显着改善其机械性能，分析了modified改性的铸造铝合金的凝固过程。为了比较with的处理效率，铝合金是通过基于钠盐的标准助熔剂进行改性的。确定相变温度和考虑到在固化范围内固相沉淀的参数。
