Abstract
Design and experimental procedures were used to demonstrate the possibility of producing by a magnetically-impelled arc a heat-treated section of a circular shape with minimum distortion and higher oil absorption. Characteristics of the HAZ under a magnetically-impelled arc have been studied, and it is shown that the region of a two-times increase of hardness goes down to the depth of 1.5 mm.
Keywords: magnetically-impelled arc, surface heat treatment, circular shape, strengthened zone, heating by a magnetically-impelled arc
