parameters were used: accelerating voltage of 12 kV, 55° take-off angle, and Si (Li) detector with an ultra-thin window. Simultaneously, standardless quantitative analysis, and ZAF matrix......
) with Cu Kα radiation on a Rigaku D/max 2550 X-ray diffractometer. The angle range was 5° to 90°. Each specimen for microstructure analysis was ground with a 5 vol.% HNO3 solution. 2.2 Immersion test......
). The microstructural morphology of the low-angle symmetrical tilt grain boundaries (LASTGBs) with θ=8.4° at different temperatures is shown in Fig. 4, presenting that the structure of dislocation pairs...) with a total of 10 dislocation pairs. Each dislocation pair is composed of two edge-type dislocations with an angle of 60° [48] (the local enlarged image and their vector direction are shown in Figs......
in the specimens occurring along the plane inclined at an angle of 45° plane to the compression axis. The similar fracture mechanism has been reported by XIAO et al [53] about Ti-6Al-4V alloy. In order......
was performed using a Xpert X-ray diffraction (XRD) (diffraction angle ranges: 20°-100°, scan rate: 5 (°)/min, step size: 0.02°), and the XRD patterns were analyzed by the commercial software JADE 9......
was 0.02°, the scanning speed was 0.15 s/step, and the measurement angle (2θ) range was 20°-90°. The German Carl Zeiss Gemini SEM 300 field emission scanning electron microscope (SEM) was used to observe......
of the local fan, the dust concentration in the working area is reduced by 80%. Although the working environment at the tunnel face is largely guaranteed, the problem of the dead angle that the airflow cannot......
gas constant; Vm is the molar volume; T is the temperature; M, w and ε (θ) are phase-field parameters, with θ being the angle between the direction of the phase-field gradient and the reference......
