Reaction kinetics and phase diagram studies in the Ti-Zn system

Ti-Zn phase diagram and layers growth kinetics, have been studied at 500, 600 and 900degreesC. Linear growth has been observed. The calculated values of the growth constants K-G are: at 500degreesC, K-G = (7.5 +/- 0.3) x 10(-9) m s(-1); at 600 degreesC, K-G = (8.0 +/- 0.2) x 10(-9) m s(-1). An indication about the presence of a formerly unknown compound (Ti2Zn3) has been found out by electron microprobe analyses and optical microscopy. Homogeneity ranges (probably metastable) have been observed for some phases that are considered to be stoichiometric. (C) 2003 Elsevier B.V. All rights reserved.
