Abstract
DTA and isothermal diffusion experiments have been carried out at temperatures up to 727
C
in the Fe-Al-Si ternary system. in these experiments, we have observed the themal decomposition of the solid ternary compound
Al
5FeSi (
6) into another ternary compound,
Al
5Fe
2Si
2 (
2), and a liquid. Under the atmospheric pressure, that decomposition of
Al
5FeSi occurs at temperatures ranging hnn
C
to
C. A polythermal projection combining these new results with previously published data is given to describe the crystallisation
of ternary Al-Fe-Si liquid alloys upon slow cooling from 727
C.
