Measurements were made on the temperature rise of tensile test specimens of austenitic stainless steels undergoing plastic deformation and discontinuous flow in normal liquid helium and superfluid helium. As the strain rate increased, the ultimate tensile strength and elongation decreased and the temperature rise increased. Compared with the results in normal liquid helium, the frequency of stress drop increased and the temperature rise was suppressed in superfluid helium.
