Special Features of the Structure of Single-Crystal Refractory Nickel Alloy Under Directed Crystallization

详细

The effect of the conditions of directed crystallization (the temperature gradient and the crystallization rate) on the dendrite spacing, on the size of the particles of the hardening γ′-phase in the arms and arm spaces of the dendrites, on the volume fraction and size of the pores, on the size of the particles of the eutectic γ/γ′-phase, and on the features of dendritic segregation in a single-crystal castable refractory alloy is studied.
