<I>In-situ</I> observation of unidirectional solidification using transparent substance has been performed to investigate the growth direction of solid phase. Cell and/or dendrite, the preferred growth directions of which are not parallel to the heat flow direction, were observed with various solidification conditions. Dimensionless growth direction (π<SUP>′</SUP>=(angle between heat flow direction and growth direction)/(angle between heat flow direction and preferred growth direction)) changes from zero to unity with increasing growth velocity at a constant temperature gradient. Introducing the normalized growth velocity (<I>V</I>⁄<I>V</I><SUB>c</SUB>, where <I>V</I><SUB>c</SUB> is the critical growth velocity for breaking down a planar interface), the relation between π<SUP>′</SUP> and growth condition could be correlated and π<SUP>′</SUP> could be expressed by a unique line with respect to the normalized growth velocity. Furthermore, the growth directions of cells or dendrites under the condition of unidirectional solidification have been analyzed by the phase-field model. The calculated results agree with the experimental results and the functional relationship between growth velocity and growth direction is qualitatively explained.
