Changes in microstructure and physical properties of skutterudites after severe plastic deformation
Original language description
The best p-type skutterudites with ZT gt 1.1 so far are didymium (DD) filled, Fe/Co substituted, Sb-based skutterudites. DD0.68Fe3CoSb12 was prepared using an annealing?reacting?melting?quenching technique followed by ball milling and hot pressing. Aftersevere plastic deformation via high-pressure torsion (HPT), no phase changes but particular structural variations were achieved, leading to modified transport properties with higher ZT values. Although after measurement-induced heating some of the HPT induced defects were annealed out, a still attractive ZT-value was preserved. In this paper we focus on explanations for these changes via TEM investigations, Raman spectroscopy and texture measurements.
