1. In the cooling process, the electric power of induction heating was controlled to achieve the designated cooling patterns with cooling rates of less than 20 °C/s in the tubular specimens and less than 80 °C/s in the solid specimens. For higher cooling rates, He quenching was employed where cooling rates can be varied up to approximately 200 °C/s by changing the gas flow rate. The sample temperatures were measured with a spot-welded thermocouple in the plane of the dilatometer.
