Abstract The Gd-CoAl vertical section of Gd-Co-Al phase diagram was determined by DTA and identified by metallographic and X-ray diffraction techniques. Two eutectic temperatures, 707 and 1040 ℃ , and two intermetallic compounds, GdCoAl and Gd(CoAl)1.5,are found. This section has 2 monophase and 9 diphase regions, also, possibly, uncertain minor triphase one.

Key words: Gd-Co-Al phase diagram Gd-CoAl vertical section intermetallic compound
