FIELD: metallurgy.SUBSTANCE: ingot is subjected to swaging-drawing to octahedron with total reduction of 1.6-1.7. Final forming is performed at shaped hammers at 4-5 displacements over hammer surface and, then, in closed sizing die. Total reduction ay final forming makes 3-5.EFFECT: precise forged pieces with homogeneous fine-gram structure, high specific strength and ductility.2 cl, 2 tbl, 1 ex |
