Tb metal was prepared by intermediate alloyed method then purified by vacuum distillation in order toobtain high-purified Tb metal used for magnetic functional materials.

Rapidly Solidified AlSr Master Alloys and Its Modifying Effect;

The paper introduces the master alloys ,the sorts and the producing methods of master alloys and alsoanalyses the research status and prospect of master alloys.

Al-Ti-C master alloys have been prepared by thermal explosion mode of self-propagating high-temperature synthesis (SHS ) using Al,Ti and C powder.

The method of intermediate alloy-vacuum distil lation for preparing high-purity dysprosium metal has been studied The influences of raw material purity and impurity removal by vacuum distillation were discussed.

This paper discusses intermediate alloy to minishment of crystal grain and the present condition of aluminium alloy On basis of analysis theory of minishment,new AlTiBRe intermediate alloy is studied for the first step The result shows that AlTiBRe intermediate alloy is the first kind efficiently long-last additive,its result is better than importing A15Ti

The results show that it is applicable to adopt the process flowsheet of HF gas fluoridization-preparation of intermediate alloy-vacuum distillation-low temperature-high temperature vaccum distillation for commercial production of high-purity Dy.
