Developing Alloy Compositions for Future High Temperature Disk Rotorsy, RR1000, and be produced using powder metallurgy and isothermal forging to enable forgings to show a consistent coarse grain microstructure. Small pancake forgings of the new alloys and RR1000 were made and from these, blanks were cut, solution heat treated, cooled at measured rates and aged. Resu

Segregation of Solutes at Dislocations: A New Alloy Design Parameter for Advanced Superalloysmperatures between 850 and 1160 °C and various deformation conditions. These interactions, and consequently the composition of a particular solute that segregates at a crystal defect, are controlled by the type of the crystal defect, the deformation conditions, i.e., temperature and stress, and the

Ni–Co-Based Wrought Superalloys Containing High W—Microstructure Design for a Balance of Propertiesmperature strength and environmental resistance at temperatures above 927 °C (1700 °F). While alloys with high Co/Ni ratios possess superior creep resistance, reductions of the Co/Ni ratio and additions of Fe and B are effective in improving ductility in the intermediate temperature range and hold-t

On the Influence of Alloy Composition on Creep Behavior of Ni-Based Single-Crystal Superalloys (SXs) referred to as ERBO/15 and ERBO/15-W, which differ in W content. The microstructural evolution of the three alloys during heat treatment and their creep behavior is investigated. When one applies one heat treatment to all three alloys, one obtains different ./.′-microstructures. Subjecting these th

Development and Application of New Cast and Wrought Ni-Base Superalloy M647 for Turbine Diskew of the microstructure and the properties of M647. A full scale forging process has been developed with uniform fine grain distribution. The detrimental effect of thermal exposure at 700 °C ~ 800 °C on mechanical properties was evaluated. M647 showed good mechanical properties and equivalent therm

Alloy Design and Microstructural Evolution During Heat Treatment of Newly Developed Cast and Wroughtres and reasonable hot deformability. Conventional Ni-base superalloys are known to be strengthened by primary, secondary, and tertiary .′, but optimal heat treatment is dependent upon specific chemical composition. For optimal mechanical properties, microstructural evolutions including austenitic .
