【 摘 要 】
The influence of growth rate on a morphology, distribution and crystallographic relationship of the intermetallic phase Zn16Ti in Zn-Ti0.1-Cu0.1 single crystals were investigated. The crystals obtained at rates in range of from 1.8mm/h to 16mm/h were tested. In all cases a strong elongation of the Zn16Ti particles along the [11-20] direction is observed. Moreover, it is found that a lamellar phase existing in the crystals develop in range of the growth rate from 6 to 10 mm/h and grows in the {10-11}planes. In the case of the growth rate of 16mm/h oval-shaped areas of α phase (solid solution of zinc and 0.1wt.% of copper with trace content of titanium) elongated along [10-10] direction and surrounded by needle shaped precipitations are formed in the structure.
