Both mechanisms can lead to the formation of low-angle boundaries. In both cases, further growth of a dendrite takes place due to the secondary arms that are perpendicular to the primary arms. The higher angles prevent a further growth of the primary dendrite arms without a change in the growth direction. For lower angles, the dendrite primary arms may slightly change their growth direction near the surface, thereby creating areas of internal stress, and then stop.

The character of interactions may depend on the angle between the axis of the dendrite primary arms and the mold surface. Additionally, the inclination of the airfoil surfaces in relation to the Z axis of the rotor blade makes the growing dendrites contact the mold walls and interact with them. Therefore, even if the mold walls are parallel to the Z, this means the dendrites can contact them. ĭuring directional crystallization, the dendrites grow directly toward the -type direction, which is only close to the blade axis Z. Due to similarity between the structure of both phases and the possibility of obtaining a clear X-ray diffraction pattern, the blades can be recognized as single-crystalline blades. The dendrites and interdendritic areas that are formed during the Bridgman process mainly consist of the Ni-based γ primary solid solution and the Ni 3Al-based γ’ secondary solid solution. The blades are obtained through directional crystallization using the temperature and withdrawal parameters that allow the formation of an array of dendrites nearly parallel to the blade axis, with the crystal orientation of each dendrite being parallel to the axis. The single-crystalline rotor turbine blades, which have a very complex shape, are usually produced by using the Bridgman technique. The single-crystalline parts made using the CMSX-4 superalloy possess high strength properties, even at high temperatures, which is especially important for turbine rotor blades, as these types of blades are exposed to harsh working conditions.
