Clean recycling of spent nickel-based single-crystal superalloy by molten magnesium
Nickel-based single-crystal superalloys are designed for extreme conditions due to their superior corrosion and creep resistance properties. However, these pose challenges in the subsequent recycling after reaching their end-of-life. Molten magnesium (Mg)

Multicomponent Rare‐Earth Monosilicate Reactions With Calcium‐Magnesium Aluminosilicate
ABSTRACT High‐temperature reactions of multicomponent rare‐earth monosilicates (REMS) with calcium‐magnesium aluminosilicate (CMAS) were investigated at 1300°C for 24 h. Three compositional series were tested, each ranging from 1‐cation to 4‐cation REMS, with cations selected to interrogate compositional effects on CMAS reactivity. The final members of

Prediction of recrystallisation in single crystal nickel-based superalloys during investment casting
Production of gas turbines for jet propulsion and power generation requires the manufacture of turbine blades from single crystal nickel-based superalloys, most typically using investment casting.

Application of single crystal superalloys for Earth-to-orbit propulsion systems [PDF]
Single crystal superalloys were first identified as potentially useful engineering materials for aircraft gas turbine engines in the mid-1960's. Although they were not introduced into service as turbine blades in commercial aircraft engines until the ...

Biaxial constitutive equation development [PDF]
In developing the constitutive equations an interdisciplinary approach is being pursued. Specifically, both metallurgical and continuum mechanics considerations are recognized in the formulation.

On the structure of defects in the Fe7Mo6 $\mu$-Phase
Topologically close packed phases, among them the $\mu$-phase studied here, are commonly considered as being hard and brittle due to their close packed and complex structure.

Heat Capacity Measurements and Thermodynamic Assessment of the Y2O3–Ta2O5 System
ABSTRACT Phase equilibria in the Y2O3–Ta2O5 system play an important role in the development of new materials for thermal barrier coating (TBC) applications, with higher thermal stability resulting in more efficient gas turbines with reduced exhaust gas emissions.
