Abstract
The formation of different types of gas pores has been investigated by directional solidification experiments. A mathematical model of pore growth has been derived and the calculated pore growth has been compared with experimental data and a good correlation was found. The nucleation process of pores has also been treated. It was shown that micropores can be homogeneously nucleated in an interdendritic area according to the pressure drop caused by the solidification shrinkage.
