The freezing of some continuous binary eutectic mixtures

摘要: Abstract Directional freezing experiments have been carried out with the binary eutectic mixtures, Al–Ag2Al, Al–CuAl2, Al–Zn, Al–Al3Ni, Ag–Cu, LiF–NaF and NaF–NaCl. Various aspects of solidification are discussed particular reference to importance solid interfacial energy. The work is divided into three parts. I. A description observed microstructures, discussion type dispersion occurring in unmodified eutectics modification lamellar arrangements by impurity cell formation. II. An account development preferred orientations during directional some eutectics. III. Measurements interphase separations as functions rates a influence energy upon these.
