为了寻求Al—Si合金的更好的变质剂,我们系统地研究了元素碲(Te)的变质作用。根据约200多炉次,近1000根机械性能试棒的实验表明:Te是Al—Si合金中共晶Si相的性能优越的长效变质剂。
In an attempt to find a better modifier of Al-Si alloys, we systematically studied the metamorphism of elemental tellurium (Te). According to about 200 heats, nearly 1000 mechanical properties of the test bar experiments show that: Te is Al-Si alloy eutectic Si phase superior performance long-acting modifier.
