Abstract
Scanning and transmission electron microscopy have been used along with x-ray diffraction in the Al - Pd - Fe system to establish a new type of B-centered rhombic N phase. The lattice constants of the N phase are as follows: a = 2.31 nm, b = 1.60 nm, and c = 4.70 nm. Electron-probe microanalysis establishes the composition: Al76.6Pd10.0Fe13.4. Differential thermal analysis indicates that the N phase melts incongruently at a temperature close to 885°C.
