Phase and structural transformations in heat resistant intermetallide nickel-based alloy

The paper studies single crystals of heat resistant intermetallide nickel-based alloy, microsegregation alloying elements within dendritic cells. The parameters of the lattices γ′ and γ phases are determined at room temperature by X-ray structural analysis. Alloying elements W, Cr, Mo and Co concent...

Description
Summary:The paper studies single crystals of heat resistant intermetallide nickel-based alloy, microsegregation alloying elements within dendritic cells. The parameters of the lattices γ′ and γ phases are determined at room temperature by X-ray structural analysis. Alloying elements W, Cr, Mo and Co concentrate in the dendritic branches. It is shown that long-term (up to 690 h) creep tests in the temperature range of 1000–1200°C hardly change the phase composition of VIN3 alloy.
