Physics of “poker” effect

In the paper, a physics of the “poker” effect was investigated experimentally and discussed by authors. Some unusual effects were discovered during experiments when heated end of the probe was quenched in an electrolyte of the optimal concentration. It’s impossible to explain the results obtained using solutions of the parabolic heat conductivity equation. The physics of the “poker” effect can be clearly explained if to take into account an existence of free electrons in the metal and the instant formation of a double electric layer. It is shown that the discovered effects can be used for an accurate evaluation of the relaxation time, which is constant for a given material. The discovery can be also used for predicting film boiling processes. A proposal is formulated to combine the evaluation of the material physical properties and Jominy curves. The importance of continuing further theoretical and experimental investigations in this field is underlined.
