摘要：
A model of crystal detachment from a chilling solid surface with vibration has been presented according to the mechanical analysis of the primary phase of a growing crystal grain. The model indicates that the main factors of crystal detachment are vibration frequency and amplitude as well as cooling temperature of the chilling solid surface. The effects of the above three factors on the actual crystal detachment behaviors were studied experimentally by using a transparent NH4Cl-70%wtH(2)O alloy. The consistency between the experimental results and theoretical study proves the mechanical model.
