摘要：

The jumplike deformation of stainless steel specimens in liquid helium was shown to be accompanied by local heating with an increase in the temperature to similar to 80 K at each serration. Measurements were performed with wire strain gages glued on the specimen and used in the range of small deformations to determine the elastic modulus and yield point. In the range of deformations epsilon similar to 0.06-0.08, the strain gages were unloaded spontaneously because of the destruction of the glue layer and responded only to variations in the temperature of the specimen at a serration.
