Analysis of the dispersion of the sound velocity in supercooled water
نویسندگان
چکیده
2014 The sound velocity in water has been measured at ultrasonic and hypersonic frequencies and the results show a negative dispersion in the supercooled region. We present measurements of sound velocity and absorption obtained by Brillouin light scattering which show that the effect of structural relaxation is not observed at 0 °C and frequencies smaller than 7.2 GHz. A correction of the hypersonic data shows that there is no apparent disagreement between the ultrasonic and the hypersonic data. J.

Brillouin scattering from supercooled water
2014 We present new experimental results for sound velocity and sound absorption of supercooled water in the temperature range down to 2014 20 °C. The results show a rapid variation with temperature that can be analysed according to equations analogous to the critical phenomena laws.

متن کاملDispersion of Love Wave in a Fiber-Reinforced Medium Lying Over a Heterogeneous Half-Space with Rectangular Irregularity
This paper concerned with the dispersion of Love wave in a fiber-reinforced medium lying over a heterogeneous half-space. The heterogeneity is caused by the consideration of quadratic variation in density and directional rigidity of lower half-space. The irregularity has been considered in the form of rectangle at the interface of the fiber-reinforced layer and heterogeneous half-space. The dis...
متن کاملInfluence of Aging Temperature on Mechanical Properties and Sound Velocity in Maraging Steel M350
In the present work, the influence of aging temperature on mechanical properties and sound velocity of Maraging steel M350 was investigated. For this purpose, first, samples were solution annealed at 825◦C for 2 hours and then age hardened at 510◦C-600◦C for 3 hours. Hardness, tensile and impact tests were used for determining mechanical properties and longitudinal ultrasonic velocity was used ...
