Experimental partial phase diagram of the Zr-Sn-Fe system

Results of the experimental study of the phase diagram of the zirconium tin-iron ternary system are presented. The existing phases and their equilibrium relationships in an extended area of the Gibb's triangle, for 800 and 900 degrees C isothermal sections, are analyzed. For the experimental work, a set of ternary alloys was designed, produced and examined by different complementary techniques: quantitative analysis with electron-probe microanalysis (EPMA), qualitative analysis with electron scanning microscopy and X-ray energy dispersive spectrometry (EDS), X-ray diffraction and metallographic examination (with optic and electronic microscopy). Phase transformations associated with the Zr-rich region of the system were investigated with electrical resistance vs. temperature measurements. The resultant ternary phase diagram is outlined.
