Mechanical and Crystallographic Texture Features of Half-Heusler TiCoSb and Based Alloys / A.El-Khouly, S.M.Amer, T.Lychagina, D.Nikolayev, [a.o.]. – Text : electronic // Journal of Alloys and Compounds. – 2025. – Vol. 1037. – P. 182539. – URL: https://doi.org/10.1016/j.jallcom.2025.182539. – Bibliogr.: 37.
Recently, TiCoSb alloys have become important thermoelectric materials because of their interesting mechanical and thermal properties. In this piece work, we present a comprehensive study on crystal structure, crystallographic texture and mechanical properties of TiCoSb, Ti&sub(0.8)Nb&sub(0.2)CoSb and Ti&sub(0.6)Hf&sub(0.2)Nb&sub(0.2)CoSb half-Heusler alloys. As known, the degree of crystal ordering is one of the most important features for Half-Heusler alloys which can be revealed via studying the crystallographic texture. Also, polycrystalline half Heusler alloys are known for defect-dominated scattering of electrons which highly confine the optimization of their electronic properties. Therefore, the crystallographic texture of Ti&sub(0.6)Hf&sub(0.2)Nb&sub(0.2)CoSb HH alloy was investigated using X-ray diffraction measurements. The crystal structure, elemental distribution and morphological properties were investigated for TiCoSb, Ti&sub(0.8)Nb&sub(0.2)CoSb and Ti&sub(0.6)Hf&sub(0.2)Nb&sub(0.2)CoSb alloys by electron microscopy combined with energy dispersive X-ray spectroscopy. Hardness of the prepared alloys has been estimated at different applied loads by the Vickers hardness method using micro-hardness technique. Significantly high mechanical stability was proved for the samples concerned. The maximum obtained hardness value was recorded for the Ti&sub(0.6)Hf&sub(0.2)Nb&sub(0.2)CoSb sample at 13.67 *( 0.55 GPa which was observed at a load of 0.98 N. All in all, Hf-Nb alloying with TiCoSb led a touchable improvement in the crystalline and mechanical properties which is expected to effectively enhance the thermoelectric performance.
