Conclusion

In commercial forgings of steel 14Kh17N2 (containing 0.35% nonmetallic inclusions) with a proportional change in the geometric parameters of the section at 20–300° the anisotropy of the ductility increases, coefficient R decreases, and the difference in the absolute values of the reduction in cross-sectional area increases with increasing forging reduction ratios due not only to an increase in the deformability of nonmetallic inclusions but also to an increase in the deformability of soft σ ferrite in the solid solution of martensite. At the forging reduction ratios investigated the distribution of nonmetallic inclusions and inclusions of σ ferrite leads to anisotropy of the ductility in the temperature range investigated.
