Phase equilibria in the Al-Cu-Fe system at a temperature of 853 K in the aluminum enriched region

Radiative strength functions for dipole transitions in 90Zr

“…Identical level densities were assumed for positive-and negative-parity states of identical spin. This assumption was recently confirmed by good agreement of the results calculated for the level density on the basis of the back-shifted Fermi gas model with experimental data obtained from the reaction 90 Zr( 3 He,t) 90 Nb for the density of levels corresponding to the 1 + states in the energy range between 5 and 10 MeV, as well as with experimental densities of 2 + and 2 − levels in the 90 Zr nucleus from high-resolution measurements of the inelastic scattering of protons with energy E p = 200 MeV at forward angles and electrons with energy E 0 ≈ 66 MeV at backward angles on 90 Zr [34].…”

Al0.88Cu0.94Fe0.18

“…crystal structure, and the lattice parameter of �-Al 50 Cu 20 Fe 30 was a = 2.925 A ˚as determined by X-ray diffraction. Kalmykov et al (2009) studied the Al-Cu-Fe phase diagram at 853 K, and considered that the lattice parameter of the �-AlCuFe phase increased with the increase of Cu content. The lowest copper content of the �-phase is 7.3 at.% corresponding to a lattice parameter of a = 2.9171 A ˚, while the �-phase with the highest copper content of 45.5 at.% has a = 2.9390 A ˚.…”

Features of the formation of a quasi-crystalline phase in Al-Cu-Fe cast alloys

“…For the Al-Cu-Fe system, in which the ico phase is stable in narrow ranges of concentration and temperature [8], no sequence of phase transitions λ (or β) ↔ i was established in cast alloys, the compo sition of which is close to that of the area of existence of the quasi crystalline phase [9,10]. The sequence of phase transitions in Al-Cu-Fe alloys needs to be studied to establish the relationship of the obtained microstructure of QC alloys and their physicochemi cal properties [11].…”
