Abstract

The quenching rate required to "freeze-in" high temperature states depends on the resolution attained in the observational technique used and on the kinetics of the property changes that may occur in the sample. For a successful quench, heat must be removed before observable changes occur. Heat loss during travel to the quench bath must be minimized as this lowers the certainty of the quenched-in temperature state, while the heat removal rate after immersion in the quench bath should be maximized. The required quench rate will determine the necessary sample size and quench medium. Quenching has been experimentally evaluated for a propelled "insulating envelope" sample transfer quench device. Results are used to determine optimum conditions for effective quenching. A procedure is established to guide the choice of sample size and quench medium to attain an adequate quenching rate.
