Circular Dichroïsm

The results of magnetometric, Mössbauer and XMCD (X-ray Magnetic Circular Dichroism) studies of B2 or DO3–type ordered (25 to 35 at.%Al) and disordered by mechanical activation (35 to 60 at.% Al) Fe-Al alloys are considered. For the description of magnetic characteristics of the studied alloys the validity of local magnetic moments models is discussed. The models suppose that Fe atom local magnetic moments are collinear with magnitude and direction depending on the number of Al atoms in the Fe nearest neighbourhood.

Linearized Augmented Plane Wave

We have performed Augmented Spherical Wave (ASW) calculations on bcc Mn and confirmed previous results by Moruzzi and Marcus who reported a ferrimagnetic phase. Independent computations employing the full-potential linearized-augmented-plane-wave (LAPW) method led to similar results. Our ASW results yield the total energy and the magnetic moments as a function of volume assuming different (ferro-, ferri-, antiferro-and non-magnetic) bcc related structures with type I, II, and III spin alignments. We relate the relative stability of various phases to band gaps that open at the Fermi energy for certain volumes. The LAPW symmetry-decomposed partial charges allow to analyze the binding mechanism.

Bcc Phase

The phase equilibria and phase transformation of the body-centered cubic (bcc) phase in the Cu–Ti–Al system were investigated by the diffusion couple method, metallographic examination, differential scanning calorimetry, and x-ray diffraction. The isothermal sections at 700 and 900 °C and vertical sections at 18 at.% Al, 22 at.% Al, and 25 at.% Al in the Cu-rich portion were determined. These results indicate that (i) the Cu2TiAl compound with the L21 Heusler structure has a larger solubility range; (ii) the stable B2 + L21 miscibility gap of the ordered bcc phase exists until the liquid phase, and the tie lines of this miscibility gap are almost parallel with the Cu–Ti side; (iii) the composition and temperature for the eutectic reaction (L ↔ B2 + L21) are about 7 at.% Ti and about 970 °C, respectively, and (iv) the velocity of the eutectoid decomposition [bcc ↔ face-centered cubic (fcc) + D83] of the bcc phase with martensitic morphology in the Cu–Ti–Al alloys is slower than that of the Cu–Al alloys.
