Iron latent heat

The terms ″sensible heat″ and ″latent heat″ refer to energy transferred between a body and its surroundings, defined by the occurrence or non-occurrence of temperature change; they depend on the properties of the body. ″Sensible heat″ is ″sensed″ or felt in a process as a change in the body's temperature. ″Latent heat″ is energy transferred in a process without change of the body's temperat… WebIn the paper the cast iron latent heat in the form of three components corresponding to solidification of austenite and eutectic phases is identified.
