Abstract
The Al-Cr phase diagram has been revisited, in the composition range from 6 to 46 at.% Al, by means of differential thermal analysis (DTA), X-ray diff raction (XRD) and electron probe microanalysis (EPMA). The intermetallic co mpounds of this system and the Cr solid solution were investigated by direc t reaction calorimetry at high temperatures. The experimental enthalpies of formation were compared with available literature data. Partial enthalpies of dissolution of Cr in liquid Al were determined at 1001 and 1106 degrees C.
