WebJun 9, 2004 · ABSTRACT The specific heat of titanium has been measured over a temperature range from 600° to 1345°K. The specific heat at 600°K is 0.72 J/g°K ±2.5%, and increases to 0.93 J/g°K ±6% just below the transition, which takes place at 1155°K. Above this point the specific heat drops to 0.75 J/g°K ±4%, where it appears to remain fairly … WebCryogenic Properties of Materials.
