Abstract

The isothermal section of the system Zr-Fe-Si has been investigated
using X-ray diffractometry and film technique. The
results were complemented with micrographic data. The existence
of the compounds found previously: Zr4Fe4Si7 (V), ZrFe2Si2 (D),
ZrFeSi (E), Zr2Fe3Si (Ai) was definitely confirmed. A new ternary
phase of the composition Zr6Fe16Sh belonging to the Mg6Cu16Shtype
was found (a= 11.53 ± 0.01 A). Zirconium stabilizes the
crystal structure of Fe5Si3 which as a pure phase exists only in
the interval from 1090 to 825° C. The isoconcentration tie-line at
66.7 a/o Zr indicates the existence of an unbroken series of solid
solutions between Zr2Fe and Zr2Si. ZrFe2 dissolves approx. 5 p. c.
of silicon. The solubility of the third component in all other
binary phases was found to be very small.
