Microstructure evolution of nanoprecipitates in half-Heusler TiNiSn alloys

Acta Materialia, 2013
Abstract The microstructures of thermoelectric TiNiSn half-Heusler alloys have been studied in detail. For concentration ratios that are slightly rich in Ni, a high density of Heusler-phase nanosized precipitates tended to precipitate within a half-Heusler matrix.

Thermoelectric properties of Ti0.3Zr0.35Hf0.35Ni1.005Sn half-Heusler alloy

Journal of Applied Physics, 2019
Thermoelectrics enabling a direct conversion of waste heat into useful electricity is widely investigated for renewable energy applications. n-type half-Heusler (HH) MNiSn (M = Ti,Zr,Hf) thermoelectric (TE) elements are known as attractive semiconducting candidates for such purposes.

Nanosized precipitates in half-Heusler TiNiSn alloy

Applied Physics Letters, 2012
The microstructure of half-Heusler TiNiSn alloy has been investigated in this study. A high density of coherent nanosized Heusler precipitates was found within the half-Heusler matrix. Formation of these Heusler precipitates occurs by a phase separation process, where a single phase solid solution (half-Heusler-Heusler) decomposes into an equilibrium ...

Dilute Magnetic Semiconductors Based on Half-Heusler Alloys

Journal of the Physical Society of Japan, 2007
We have investigated the electronic structure and magnetism of Mn-doped half-Heusler alloys by using the Korringa–Kohn–Rostoker coherent potential approximation (KKR-CPA) method within the local density approximation (LDA). Half-Heusler compounds can be attractive for spintronic applications because the crystal structure and lattice constant of these ...

Thermoelectric properties of Bi-doped half-Heusler alloys

Eighteenth International Conference on Thermoelectrics. Proceedings, ICT'99 (Cat. No.99TH8407), 2003
Based on our preliminary promising results for Sb-doped ZrNiSn-type half-Heusler intermetallics, we made a new series of Bi-doped samples Zr/sub 0.5/Hf/sub 0.5/NiSn/sub 1-x/Bi/sub x/ with concentrations x in the range 0/spl les/x/spl les/0.02. While the isoelectronic alloying of Zr and Hf reduces the lattice thermal conductivity, doping on the Sn site ...

Magnetic behavior of half-Heusler alloy CuxNi1−xMnSb

Journal of Magnetism and Magnetic Materials, 2005
Abstract We have investigated the effects on the magnetic properties of NiMnSb alloys with the substitution of Cu for Ni. The half-Heusler type alloys, CuxNi1−xMnSb compounds, are fabricated by the arc-melting method and are subsequently annealed at a temperature of 1050 K for 24 h.
