New development of the metal volume thermal expansion

Volume thermal expansion measurement of the solid is one of the most challenging issue in material industry especially when the solid is in big size. The existing instruments such as dilatometer has a limitation to determine the volume thermal expansion of material. Therefore, a new and precise syst...
