Abstract
Nanocrystalline TiCoSb powder was synthesized by mechanical alloying from elemental Ti, Co and Sb powders. The samples milled at different times were characterized by X-ray diffractometer (XRD) and scanning electron microscopy (SEM). The synthesized powder shows a half-Heusler phase in MgAgAs structure after 6 h of milling. The crystallite sizes decrease with increasing milling time. The minimum crystallite size is about 31.7 nm after 40 h of milling. The magnetic properties of this sample give evidence of the existence of ferromagnetic clusters as a secondary phase.
