A new correlation between ultrasonic shear wave velocity and Poisson's ratio has been established for isotropic solid materials, based on the data generated experimentally and collected from the literature. Poisson's ratio has been found to decrease with increasing ultrasonic velocity in various solid materials such as metals and alloys, ceramics and glasses, intermetallics and polymers. The slope...
The influence of prior tensile deformation on the magnetic Barkhausen emission (MBE) and the hysteresis (B–H) curve has been studied in 0.2% carbon steel and 2.25Cr–1Mo steel under different tempered conditions. This study shows that the micromagnetic parameters can be used to identify the four stages of deformation, namely (i) perfectly elastic, (ii) microplastic yielding, (iii) macroyielding and...
