主 题:composite-in-situ planar crystal cellular crystal constitutional supercooling curvature supercooling
摘 要:It is clarified by experimental examination and theoretical analysis that the transformation of crystal moorphology of the eutectic Al-Cu alloy composite-in-situ seems to be judged by not only the constitutional supercooling proposed in previous literatures but also the supercooling due to the effect of curved surfaces at the solidifying *** greater entropy of fusion and the tendency to faceted face are important features of the non-metallic phase,which may con- tribute to the leading,role of the phase during *** might be the change of leading phase that changes the morphology of crystals.
