The improvement of the cast part quality, meaning the geometric precission and the mechanical properties, is an important goal for researchers. There is a twofold aim: (i) the reduction of the costs related to the cast part mechanical machining and (ii) a high level of the cast part strength during functioning, by obtaining a proper crystalline structure during melt material solidification/cooling. This domain mainly refers to the relation between the melt material solidification/cooling process and the cast part crystalline microstructure. This approach has two aspects: (i) the modelling of the melt material solidification/cooling process in order to programme the optimal thermal field dynamics and the control of the thermal field evolution depending on its programmed dynamics.
