SANS Investigations of the Irradiation-induced Microstructural Changes in Surveillance Specimes of VVER-440-Type Reactor Pressure Vessel Steel 15Kh2MFA and Weld Metal Sv-10MFT

Two mechanisms are proposed for the theoretical description of the dilational viscoelasticity on a liquid surface. Possible relaxations of the temperature and electric charges induced due to the passage of the transverse-longitudinal surface waves are discussed. The dilational viscosity of the liquid metal surface can be realistically estimated from the charge oscillations model.
