The lattice misfit between γ and γ'phase is a key parameter in Ni-base superalloys.
Resulting internal coherency stresses govern the microstructure, its evolution and …

The affordability has become a key element in the development of the modern aero-engines
thus the design and research of low-cost single crystal superalloys are in great demand. A …

The interrelationships between composition, γ′ morphology, hardness and γ–γ′ mismatch
were identified for a set of advanced nickel-base polycrystalline superalloys. When cooling …

The present study aims to understand the underlying mechanisms of macroscopic
contraction that occurs in γ/γ′ nickel based superalloys submitted to isothermal annealing …

In-situ neutron diffraction measurements were performed on monocrystalline samples of the
Ni-based superalloy CMSX-4 during N-type γ′ raft formation under the tensile creep …

Elevated temperature creep behaviors at 1100° C over a wide stress regime of 120–174
MPa of a third-generation Ni-based single crystal superalloy were studied. With a reduced …

Tensile behavior of a Re-containing Ni-base single crystal superalloy with [001] orientation
was conducted at from room temperature to 1100° C, and the corresponding deformation …

Three cast alloys with compositions of Co-9Al-8W-0.1 B, Co-9Al-9W-0.1 B and Co-9Al-11W-
