Abstract [en]

In the present work, a phase diagram investigation of binary Fe-Pt alloys was carried out by means of the differential thermal analysis method. 12 different alloys were investigated with a NETZSCH STA 449C Jupiter((C))DCS unit in the temperature range of 300-1673 K and 3 alloys with a Setaram HTC 1800 K-DSC 2000 K calorimeter in the temperature range of 3001988 K, respectively. The measurements were carried out in Ar as well as H-2 atmospheres. The results obtained show a good agreement with previous investigations and bring new information for order/disorder phase transitions for FePt and FePt3 alloys, respectively, in the temperature range 1420-1610 K. Use of He instead of H-2 in some of the trials showed that the impact of hydrogen on the measurements was insignificant.
