Source abstract
Abstract
Abstract Phase relationships in the Ge-Mn-Ti ternary system have been studied through alloy samples approach. Assisted with Electron Probe Microanalysis (EPMA) and X-ray diffraction (XRD) techniques, isothermal sections at 973 K, 1073 K and 1173 K of this system were constructed and existence of 2 ternary phases, i.e. GeMnTi and Ge 2 MnTi, were confirmed. In addition, remarkable ternary solubilities in some binary compounds were detected, e.g. Ge in Mn 2 Ti and Mn in Ge 5 Ti 6 can be up to 15 at% and 50 at% at 1173 K, respectively. Furthermore, the substitution of Ti by Mn atoms in Ge 5 Ti 6 was confirmed with Rietveld refinement results of solid solutions, Ge 5 (Mn 0.30 Ti 0.70 ) 6 and Ge 5 (Mn 0.67 Ti 0.33 ) 6 .
