The influence of the high-gradient directional crystallization on the structural components (the interdendritic distance and porosity) of the superalloys is presented in the Article. The industrial-scale high-gradient plant of UVNS-6 type and some benefits of its use are shown here as well. Some test specimens manufactured on the UVNS-6 are studied with measurement of the interdendritic distance. The temperature gradient is estimated by experimental method.
