The standard enthalpies of formation of some intermetallic compounds of transition metals by high temperature direct synthesis calorimetry
Meschel,Kleppa
, p. 143 - 149 (2006)
The standard enthalpies of formation of some intermetallic compounds of transition metals have been measured by high temperature direct synthesis calorimetry at 1373 ± 2 K. The following results (in kJ/mol of atoms) are reported:{A formula is presented}. The values are compared with some earlier experimental results obtained by EMF and by calorimetry. They are also compared with the predicted values of Miedema and co-workers. We will present a systematic picture of how the enthalpies of formation may be related to the atomic number of the transition metal.
Coexistence of localized and (induced) itinerant magnetism and heat-capacity anomalies in Gd1-xYxNi alloys

The results of magnetization (A/), electrical resistivity (p), and heat-capacity (C) measurements for the alloys, Gd1-xYxNi, are reported. The x-ray-diffraction patterns indicate that there is a change in the crystal structure from CrB-type to FeB-type orthorhombic structure for increasing x near Jt=0.4. GdNi has been known to order ferromagnetically at 70 K and the observed jc dependence of Tc and 6p proves that the strength of Gd-Gd exchange interaction is enhanced by a factor of about 1.5 in the FeB structure. The A/ data suggest that there is an excess moment for the Gd-rich alloys. The observed magnetization behavior is taken as an evidence to show that there is coexistence of localized magnetism (from Gd) and itinerant ferromagnetism of induced-type, presumably from Ni 3d band. There is an enhancement of C with decreasing temperature above TC oyer a wide temperature range presumably due to short-range order effects in these alloys.

The isothermal section of the phase diagram of the ternary system Y-Ni-V at 773 K was investigated by X-ray diffraction (XRD), scanning electron microscopy (SEM) and energy dispersion spectroscopy (EDS) techniques. It consists of 16 single-phase regions,
Improvements of hydrogen storage properties of Mg-based mixtures elaborated by reactive mechanical milling
Bobet,Chevalier,Song,Darriet
, p. 570 - 574 (2003)
The influence of mechanical grinding under hydrogen (Reactive Mechanical Grinding=RMG) on the chemical properties (crystallographic and phase composition) and on the hydrogen storage properties of Mg-based mixtures is examined. Different additives were st
