The fine structure of spontaneous deformation jumps and jumps initiated by both the shock action on a deformation device and a strong fast-changing magnetic field (up to 2.7 MA/m) has been investigated in metals and alloys at liquid-helium temperatures. Oscillography of the signals of changes in the load on the sample and of acoustic emission has made it possible to reveal the relationship between types of jumps and postulate on the mechanism of their appearance.
