Notes:
In this study, we investigate the crystalline states and conditions for thegrain-refinement of Bi70Sb30 (at.%) alloy. It was considered under an ultra strong gravity field, thecrystals were fine-grained from the primary grain sizes of several mm to several tens of mm, andthe crystal growth followed with formation of graded-composition structure due to sedimentationof atoms along the direction of gravity. It was found that for the crystal-grain refinement inBi70Sb30 alloy the minimum gravitational field and the minimum time duration were at least160,000 G and 10 hours, respectively at about 200 ºC
