electron microscope (Hitachi S-4700, Hitachi, Japan, FESEM) at 10 kV, and transmission electron microscope (Tecnai G2 F30 S-Twin) at an accelerating voltage of 300 kV. N2 adsorption/desorption isotherms......
of deformation parameters on microstructure evolution, optical microscope (OM) and electron backscatter diffraction (EBSD) technology were carried out. For OM observation, the metallographic specimens...% CH3OH and 20% H2SO4 at 20 V for 10-15 s. OM study was conducted on an optical microscope (Olympus GX71). EBSD study was conducted on a Quanta 200FEG-SEM scanning electron microscope equipped with OIM......
of material processing Precipitates were observed through transmission electron microscopy (TEM). The TEM foils were parallel to the rolling plane and prepared by mechanical grinding and twin-jet... through conventional bright-field (BF), dark-field (DF) imaging, and selected area electron diffraction (SAED). 3 Results 3.1 Tensile properties Figure 2 shows the yield strength, tensile strength......
stress were described by the creep equation. Electron back-scattered diffraction (EBSD) technique was used to observe the microstructure and texture evolution during hot tensile deformation... electron microscope with 0.2 μm step size, and analyzed through the HKL-Channel 5 software. Tensile specimens with a gauge length of 25 mm and a width of 6 mm were machined from the sheet along the rolling......

provides a meaningful discovery for predicting rockburst. 2 Experiment and methods 2.1 Experimental equipment The experimental equipment includes a VEGA scanning electron microscope (SEM), an energy... in the micro zone through SEM and EDS analysis. Figure 4 shows SEM images of a granite sample at magnifications of 200 times, 500 times and 2000 times. The secondary electron image (SEI) clearly shows......
identified using scanning electron microscopy (SEM). Then, the cracking mechanism of the surrounding rock was quantitatively investigated. However, the failure process and mechanism of tunnel rockburst... and a depth of 100 mm was drilled in the center of the specimen (Figure 1(c)). Figure 1 Scanning electron microscopy image of granite fragments (a), uniaxial compressive strength of granite specimen (b......
processes of Longmaxi shale and Beishan granite [9] under a scanning electron microscope. In terms of microstructure, Longmaxi shale is finer than Beishan granite, with less granular particles and more..., however, it did not influence the overall trend. Figure 7 Crack morphologies of two rocks under scanning electron microscope: When subcritical crack length reached its maximum △amax, the crack would......
electron microscope (SEM) and CT imaging methods, the digital speckle method can realize the non-contact, high precision and automatic measurement, at the same time, has low requirements... specimens by the scanning electron microscope (SEM). The results show that the specimens with zigzag crack propagation path account for more intergranular fracture, while the specimens with straight......
characterization Surface morphologies of the obtained coatings were observed using field-emission scanning electron microscopy (FE-SEM, Nova NanoSEM 450, USA). The composition of element was determined by equipped energy dispersive X-ray spectrometer (EDS). The chemical bonds in the coating were characterized by Fourier transform infrared spectrophotometer (FTIR, Nicolet 380, Thermo Electron......
