Abstract:
It is gradually getting clear that the macroscopic description of materials requires additional thermodynamic parameters, entropy of microstructure and temperature of microstructure. It was claimed that there is "one more law of thermodynamics": entropy of microstructure must decay in isolated thermodynamically stable systems. Such behavior is opposite to that of thermodynamic entropy. This talk will illustrate the concepts of microstructure entropy and microstructure temperature by several physical examples. The experiments will be described that confirm the decay of microstructure entropy in grain growth of polycrystals.
