Effect of high-gradient directed crystallization on the structure and properties of rhenium-bearing single-crystal alloy
The effect of directed crystallization with high temperature gradient at the growth front on the structure, dendritic segregation, porosity, and high-temperature strength of a recent rhenium-bearing refractory alloy with single-crystal structure used for casting GTE blades is considered.
