“…These drawbacks do not exist for experiments at constant temperature and/or longer dwell times, such as creep and stress relaxation in similar alloys [17,18]. Finally, studies requiring access to high temperature furnaces are complex as a number of experimental issues need to be overcome; this includes oxidation & corrosion effects, suitable sample monitoring including specialised thermocouples & strain gauges as well as thermal scattering associated signal attenuation effects.…”

“…Therefore, the measurement of residual stress is of great significance in engineering. Wu and Sun et al conducted many studies of the DD10 single crystal superalloy using neutron diffraction measurement [21,22]. Their investigation found that the evolution of the microstructure and the residual stress in DD10 superalloy showed correlation for different creep stages.…”

“…Therefore, the diffraction peak position of the quenching sample will contain residual stress shifts to some extent, compared with the initial stress-free sample. reflection which was suitable to measure the long-range internal stress in materials, and thus was chosen as the diffraction crystal plane [21]. The neutron wavelength was 1.593 Å, and thus the diffraction angle was ~90° to define a cubic gauge volume of 2 × 2 × 2 mm 3 .…”

“…In the last 20 years, works have been conducted to investigate the strain/stress state in SC nickel-based superalloys. The strain/stress state of Ni-based SC superalloy samples that went through thermo-mechanical fatigue, creep-deformation, and shot-peening have been experimentally studied [15][16][17]. B. Marty.…”

“…In the previous works dealing with Ni-based SC superalloys strain/stress research, the macro-stress was always involved, and its correlations with the material performance were discussed [15][16][17]20]. However, the Ni-based SC superalloys were composed of an fcc γ-matrix and coherently aligned L1 2 -ordered γ -precipitates and had a unique two-phases mismatch structure [21,22], which has not been taken into consideration in the aforementioned works.…”
