Effect of HPT processing on the structure, thermoelectric and mechanical properties of Sr0.07Ba0.07Yb0.07Co4Sb12

[Display omitted] ► TEM images of an n-type skutterudite after HPT processing are shown for the first time. ► Dislocations and grain boundaries of two types could be detected. ► Microhardness is enhanced after HPT processing revealing Hall–Petch strengthening. ► Thermal expansion of an HPT processed...
