Abstract
The results of fatigue tests of samples made of D16T aluminum alloy, treated by magnetic-pulse hardening (MPH) and the passage of a high-voltage pulsed electric current, are presented. It is shown that MPT increases the cyclic durability of samples by 2...2.5 times, regardless of the considered modes and hardening schemes during fatigue tests with loading by symmetric cantilever bending. However, there is a slight increase in fatigue life dissipation after this treatment. Passing a high-voltage pulse current through the sample increases the cyclic life by 1.9-2.4 times at a stress amplitude of fatigue tests of 320 MPa.
