The thermosolutal convection during directional solidification of multi-element compound crystals alloy in vertical Bridgman configuration arises from the interaction between temperature and solute gradients in the bulk melt.
结果表明:在垂直Bridgman装置中,熔体的热质对流是由于生长炉热边界条件的不连续性和晶体熔-固两相热物性不匹配引起的;随着熔体流动强度的增加,径向溶质分凝出现两个极小点,所以单纯地抑制或加强熔体对流强度并不一定能改善径向溶质分凝现象。
