The Influence of the Mechanical Vibrations upon 1.7035 – 41Cr4 Steel during Hardening Process

Abstract:

After a number of experiments it was noticed that mechanical vibrations affect the process of austenite on cooling conversion. The behavior of 41Cr4 steel was studied during the hardening process in mechanical vibrations action environment. At low power of sinusoidal signal excitation, respectively at low amplitudes of test samples oscillations, a hardness increase can be observed, as well as on surface and in depth. By exciting the test samples on different resonance frequencies, when the oscillations amplitude is higher, it is obvious that the hardness of cooling surface remains high while the depth hardness decreases. This presumes a growth of resistance to abrasion and improvement of product toughness. By modifying the influences of the excitation system, the frequency and the power of the mechanical excitation generator can be achieved, both on test samples and different products, superior results about toughness, resistance to abrasion and endurance strength.
