Performance comparison of Ca,Ba-inoculant vs Ca,Ce inoculant in spheroidal graphite iron

In the present study, the performance of Ca, Ba-inoculant has been compared against Ca, Ce-inoculant in spheroidal graphite irons (SGI). In the study, the addition rate for the two inoculants was varied in order to understand what the minimum addition rate would be to ensure carbide free castings and to evaluate the effect of increasing inoculant addition on carbide level, graphite structure and thermal analysis characteristics.
