Stable longitudinal sinusoidal vibrations of the resonant frequen-cies of different orders of the solidification system were introduced to it toinvestigate the influence of vibrations on the temperature profile in the li-quid phase during solidification.It was found that,as compared with the caseof static solidification,the temperature profile in the liquid phase was changedand the temperature gradient was decreased due to the vibration introduced.Experiments indicate that the first order resonant frequency...
