Microstructural Stability and Evolution in a New Polycrystalline Ni-Base Superalloy
Metallurgical and Materials Transactions. A, 2023 Polycrystalline Ni-base superalloys that offer equivalent or superior performance to current commercial alloys at lower overall cost are of widespread industrial interest. In this work, a new polycrystalline Ni-base superalloy with low elemental cost has

Segregation-Assisted Plasticity in Ni-Based Superalloys [PDF]
Metallurgical and Materials Transactions A, 2018 Abstract Correlative high-resolution transmission electron microscopy and energy-dispersive X-ray spectroscopy are used to study deformation-induced planar faults in the single-crystal superalloy MD2 crept at 800 °C and 650 MPa. Segregation of Cr and Co at microtwins, anti-phase boundaries (APB), and complex/superlattice extrinsic and ...

Stress corrosion of Ni-based superalloys [PDF]
Materials at High Temperatures, 2017 AbstractThe development of gas turbines to increase fuel efficiency is resulting in progressively higher operating temperatures in the under platform regions of the blades. These regions have traditionally been considered low risk areas. However, higher metal temperatures combined with stresses and the deposition of contaminants from the cooling air ...
