The effect of tantalum on the structure/properties of two polycrystalline nickel-base superalloys B-1900 + Hf and MAR-M247 [final report] /

The effect of tantalum on the structure/properties of two polycrystalline nickel-base superalloys B-1900 + Hf and MAR-M247 [microform] : [final report] / by Gregg M. Janowski, prepared for National Aeronautics and Space Administration, Lewis Research Center under grant NAG 3-216.

The microstructure, phase compositions, and phase fractions were studied in conventionally cast B-1900 Hf and both conventionally cast and directionally solidified MAR-M247 as a function of tantalum concentration. The hot tensile and creep rupture properties of the solutionized and aged MAR-M247-ty...
