For directional solidification of the alloy, both in the original state and after heat treatment to produce a more uniform structure (1230-1270°C, 1 hr, cooling at 50 deg/min), the γ/γ′ matrix includes colonies of orderly distributed, long, straight and highly anisotropic crystals of a kind not typical of polycrystalline materials. In contrast to polycrystalline materials of the same type, microdiffraction analysis showed a strict orientation relation between the crystal lattices of the γ phase and MC carbide.",
