ABSTRACT

The results of a study of the dependences of the inductor current and heating kinetics on the power consumption value for titanium samples in the course of treatment with high frequency currents in the range from 88 to 120 kHz were presented. The effect of the inductor current in the range from 0.3 to 8.5 kA on the heating kinetics of equimass samples of disk and cylindrical shapes in the temperature range from 800 ºC to 1500 ºC in air was established. It was shown that the kinetics of a one- and two-cycle induction treatment had differences at the alpha-phase temperature.
