      In this study, we investigated the catalytic properties of various Heusler alloys for the hydrogenation of propyne and the oxidation of carbon monoxide. For propyne hydrogenation, Co2FeGe alloy showed a higher activity than that of elemental Co, where neither Fe nor Ge showed any activity. This clearly indicates an alloying effect. For the oxidation of carbon monoxide, although most alloys. IN the course of a comprehensive examination of the Heusler alloys it has been found that the alloy Cu 2 MnSb, previously reported as ferromagnetic 1, shows some of the properties of an.

    The MNiSn (M = Ti; Zr; Hf); half-Heusler semiconducting alloys have a high potential for use as n-type thermoelectric materials at elevated temperatures (~ K). The alloys’ durability is crucial for their commercial handling and use, and therefore it is required to characterize their surface oxidation behavior and stability at the working temperature. X-ray photoelectron spectroscopy. We performed combined theoretical and experimental studies of electronic, structural, and magnetic properties of Fe 2 MnSn Heusler alloy. The density functional theory calculation shows that the Fe 2 MnSn alloy has two energetically close phases, namely, hexagonal D0 19 and cubic L2 1, which agrees well with the experimental the hexagonal and cubic phases are ferromagnetic, with.

    The effect of disordering, particularly Cr clustering on the magnetic properties in bulk and nanosized Heusler alloy Fe 2 CrAl has been studied using a combination of X-ray diffraction, 57 Fe Mössbauer spectroscopy, and DC magnetization. The structural order/disorder has been confirmed using Mössbauer spectroscopy, and the observed bulk magnetic properties have been correlated to these results. Tantalum and its alloys have received increased interest as a model bcc metal and for defense-related applications. The stress-strain behavior of several tantalums, possessing varied compositions and manufacturing histories, and tantalum alloyed with tungsten, was investigated as a function of temperature from {minus} C to 1, C, and strain rate from 10{sup {minus}3} s{sup {minus}1} to.

This book gives an overview of the physics of Heusler compounds ranging from fundamental properties of these alloys to their applications. Especially Heusler compounds as half-metallic ferromagnetic and topological insulators are important in condensed matter science due to their potential in magnetism and as materials for energy conversion.

From the paramagnetic behaviour of the Heusler alloy in the liquid as well as solid states, the same magneton number n' eff ⋍ 5 per Mn atom results. Structural properties Heusler alloys are defined as the ternary intermetallic compounds.

At the stoichiometric composition, full Heusler alloys (X2YZ) and semi Heusler alloys (XYZ) crystallize in L21 and C1b structures (see figure), respectively. The elements normally associated with the X, Y and Z are indicated in table1.

The research combined ab initio Density Functional Theory (DFT) calculations with experimental microstructure evaluation and measurements of the transport properties up to K.

It is shown that Al addition to the Ti sub-lattice results in an increase of the absolute value of the Seebeck.

The HH CrVSe alloy is found to have the lowest direct bandgap (E B G) of eV with a comparatively highest half-metallic gap (E H M) of eV, due to the d-d hybridization.

Our calculated cohesive (E C) and formation (E f) energies indicate the chemical and thermodynamic stability of the studied HH CrVZ alloys.

A new Mn-based Heusler alloy Mn2CuAl has been synthesized by the melt-spinning method. It has an ordered bcc structure and is a ferrimagnet with a saturation moment of µB/f.u. at 5 K. The Fe2VAl Heusler alloy was reported to have good thermoelectric properties. Because the natural resource of vanadium is insufficient, Fe2TiAl based alloys were studied.

In order to produce new β (bcc) Ti alloys for medical applications, effects of Mn substitution for Cr on phase constitution and mechanical properties of Ti-Cr-Sn alloys were investigated. All the Ti-7mol%(Cr, Mn)-3mol%Sn alloys investigated by XRD analysis were identified as β (bcc) alloys, and athermal ω phase was also detected in Ti-7mol.

The FeCoNiMn alloy prefers to form L1 2 structure to diminish the magnetic frustration. In the L1 2 structure, Mn minority spin peak moves from above to below Fermi level, further increasing Mn magnetic moment. For FeCoNi(MnAl) x alloys, the alloy structures change from FCC to BCC with the increase of Mn and Al content.
