Italian term or phrase: sosta termica
Sosta termica: durante il passaggio di stato coesistono lo stato solido e lo stato liquido e nonostante si continui a somministrare calore la temperatura rimane costante fino a quando tutta la sostanza non è diventata liquida, per poi risalire fino al prossimo passaggio di stato.
Si verifica la sosta termica perché il calore fornito serve per vincere le forze di coesione, questa quantità di calore assorbita durante il passaggio di stato è il calore latente, calore nascosto.
Pertanto fornendo calore ad una sostanza, ad un certo punto si dovrà osservare nei dati di temperatura una sosta termica che coincide con il punto di fusione.

isothermal period/stage/time
Explanation:
Suppose we heat a solid piece of metal. The atoms vibrate increasingly as the temperature is raised and this shows as an overall expansion of the metal. At a certain temperature the amplitude of the vibrations is such that the bonds between the atoms are broken and the atoms are free to move from their previously fixed positions. This is known as the melting point and the metal remains at steady temperature, despite the fact that heat is still being applied, until all the solid atoms become molten. This take up of energy is known as "latent heat of fusion" and it is defined as the energy required to change a solid metal to liquid at the fixed temperature known as the melting point.

trovo anche isothermal hold/holding

(o, più in generale, si potrebbe anche dire isothermal state or condition)

sosta here means a time span (during which no heat changes are recorded), "phase" in the context would be understood as, say, solid vs liquid phase - that's why i didn't put it in
