Název v původním jazyce
Thermal stability of half-Heusler (Ti,Nb)FeSb alloys
Popis výsledku v původním jazyce
Half-Heusler (H-H) alloys are known for their thermoelectric properties which can be optimized by doping the three individual sublattices with suitable elements. If volatile elements such as Sb or others are involved, the study of vaporization characteristics for long term thermal stability of these materials is of practical importance. This contribution presents a study of thermal and phase stability of H-H alloys, (Ti,Nb)FeSb, prepared by hot pressing or by ball milling and hot pressing, by means of thermal analysis and the Knudsen effusion method. The results supported by data from microstructure measurements and the measurement of the diffusion profiles are discussed in view of phase diagrams of the respective ternary systems and results of our previous investigation of the long term thermal stability of didymium doped p-type skutterudites.
