In-situ testing of surface evolution of SiC during thermal ablation: Mechanisms of formation, flowing and growth of liquid silica beads

High Temperature In Situ Optical Observation and Structural Optimization Numerical Simulation of High Nitrogen Steel (Cr18Mn18N)

“…In the high-temperature arc wind tunnel, the surface parameters of the specimen cannot be obtained by conventional optical observation techniques owing to high-temperature radiation, airflow interference, and other factors. Therefore, in order to obtain the behavior change of the material surface, the temperature synchronous deformation measurement device is used during experiment as shown in Figure 1 b [ 22 , 23 ]. The equipment consists of a single-point infrared pyrometry (Raytek, MI3, Santa Cruz, CA, USA), a blue light source (central wavelength 465 nm), a CCD camera (SP-500-USB, JAI Ltd., Yokohama, Japan), a 75 mm lens (JAI Ltd.), and a blue bandpass filter (with central wavelength of 465 nm and full width at half maximum of 5 nm).…”
