A Study of the Effect of Magnetic Field Pulse Duration on Residual Stress and Surface Hardness of 40Kh13, R6М5, and 40KhМFА Steels
The effect of magnetic-pulse treatment on changes in the properties of steel grades 40Kh13, R6M5, and 40KhMFA depending on the pulse duration, frequency and energy characteristics of the treatment is studied theoretically and experimentally. An experimental MIU 20-21 magnetic-pulse unit capable of increasing pulse duration and changing the strength of the magnetic field is developed. Dependencies of variation in microhardness and in the surface roughness parameter Ra of the studied samples are obtained on different magnetic-pulse units with different technical characteristics and under different modes of exposure. The treatment has made it possible to reduce the surface roughness values from 5 to 26%, to diminish the spread in values of surface microhardness and to increase it up to 20%. The research into the pulsed magnetic field effect on residual stresses in samples indicates the possibility of changing them stably and repeatedly. Stresses have been completely regulated in several samples using this method of magnetic-pulse treatment.
