Co-Al-W-based superalloys may become a next generation of high-temperature structural
materials used in the hot-section of gas turbine because of the discovery of γ …

With the aim of understanding the effect of creep defects in the γ′ phase on the creep
resistance, the atomic structure and elemental segregation behavior of stacking faults (SFs) …

The present work contributes to a better understanding of the basic assumptions and
principles behind the design of Ni-based single crystal superalloys (SXs). For this purpose …

A systematic study of the compression creep properties of a single-crystalline Co-base
superalloy (Co-9Al-7.5 W-2Ta) was conducted at 950, 975 and 1000° C to reveal the …

We investigated the solute diffusional behavior active during compressive creep deformation
at 150 MPa/975° C of a Co-Al-W-Ta single crystal superalloy in the [001] orientation. We …

Chromium is known to confer oxidation resistance on Co-based superalloys. Herein we
studied the influence of Cr concentration on the properties of a Co-based superalloy, Co …

NbMoTaW refractory high-entropy alloys (RHEAs) possess superior high-temperature
mechanical strength. However, their practical applications are limited by low room …

Nanoscale solute segregation to or near lattice defects is a coupled diffusion and trap**
phenomenon that occurs in superalloys at high temperatures during service. Understanding …

The creep behavior of a multinary single crystal Co-base superalloy has been compared for
uniaxial tension and compression of 400 MPa applied along [001] at 850° C. Creep under …

The preferable thermodynamic stability of L1 2 γ'-Co 3 (Al, V) phase and wide γ+ γ'two-
phase region endow the Co-Al-V alloy with great application potential. By introducing the …
