Abstract A series of Al--Cu--Fe alloys with compositions ofAl48-60Cu33-50Fe0-10 was prepared and the phase constituents in thesealloys quenched from various temperatures were identified by using XRD, SEM, EDXS and EBSD attached to SEM, and TEM (including HRTEM). Compared with the polythermal projection proposed by Gayle et al, a main amendment is to divide the previous φ--region into β+φ two regions. A new ternary reaction is the quasiperitectic at U8: L+βIQC+φ.EDXS reveals that the composition of φ phase with Ni2Al3 structure is in Al47.3-50.6Cu45.4-48.1Fe4.5-5.2,and its center composition is Al47.9Cu47.1Fe5.0.
