Abstract
The paper presents the results of a study of the effect of extracentric liquation inhomogeneity on the mechanical properties of the forged billet of the rotary shaft of 38CrNi3MoV steel. Changing the forging mode with subsequent heat treatment affected the classical location of the extracentric liquation. The displacement of the off-center liquor led to the formation of cracks and their exit to the forging surface. Mechanical tests of samples from the defective zone showed a decrease in plastic and viscous properties by 30-47.6%.
