Enhancing thermal conductivity of TiC nanopowder with cryogenic treatment

Abstract

This paper deals with determining the thermal conductivity and thermal diffusivity of TiC nano powder before and after deep cryogenic treatment. Deep cryogenic treatment is done at −196 °C for 24 h on Tic nanopowder material. The thermal conductivity and thermal diffusivity were found out by using laser flash apparatus. It is found that the thermal conductivity of TiC nanopowder is improved by 21% due to deep cryogenic treatment.
