摘要

IN100 superalloy castings were vacuum cast with the application of multi-electromagnetic field. The effect of multiple-electromagnetic field on the solidification structure of IN100 superalloy castings has been studied. The results show that with the application of the multiple-electromagnetic field composed of the main frequency rotary electromagnetic field with 60A current and the steady direct current electromagnetic field with 290A current, the shrinkage porosity of IN100 super-alloy castings is greatly improved and the fine equiaxed grain fraction of IN100 superalloy castings is increased to 100%. Moreover, the action mechanism of multiple-electromagnetic field is discussed to explain its effect on improving the solidification structure of IN100 superalloy castings.
