latent heat of fusion

The heat required to convert 1 g of a solid to a liquid at the same temperature. For example, the process of converting 1 g of ice at 0°C to water at 0°C requires 80 cal, and, until it is completed, there will be no rise in the temperature.

The simplest way to perform a heat transfer simulation is to have the latent heat of fusion released constantly from the start of solidification to the end of solidification.

For the casting material, latent heat of fusion and the freezing range also must be specified.
Once solidification does occur, the latent heat of fusion required to remelt the metal network may provide an effective barrier and ensure that further penetration does not occur.
