摘要：

It was demonstrated that forced convection or mixing in the melt during directional solidification of bulk InxGa1-xSb (0 < x < 0.1) ternary alloys significantly reduces cracks in the crystals. In this study, the enhanced mixing in the melt was generated by a rotating submerged baffle. The resultant improvement in spatial compositional homogeneity lowers the strain gradient or chemical stresses; thus eliminating cracks. The results presented are generally beneficial and should also improve the crystalline quality of other mixed alloys. (C) 1998 Elsevier Science B.V. All rights reserved.
