摘要/描述

rature five groups of authors [1, 2, 4, 6, 7] reported an eutectic reaction type (L→(Al)+Al45Cr7), whereas the remaining two groups [3, 5] suggested a peritectic one, L+Al45Cr7→(Al). In the phase diagram assessed by Murray [11, 12], the peritectic reaction type is adopted. The purpose of the present work is to identify the degenerated nature for the invariant reaction among (Al), liquid, and Al45Cr7 by means of differential scanning calorimetry (DSC), X-ray diffraction (XRD) and electron probe microanalysis (EPMA) methods
