1. Three stages of aging are observed in cast maraging steel Kh14K9N6M5 quenched to martensite and retained austenite. In the first state (up to 550°) martensite decomposes into two solid solutions — ferromagnetic, rich in iron, and nonferromagnet

1. Aging at 700–775° induces decomposition of the solid solution by continuous precipitation with formation of β Ni3Ti (fcc lattice) in steel EP33 deformed ∼20%. 2. Under the simultaneous influence of temperature (650°) and high torsional stre

1. Plastic deformation together with rapid coding of KhN77TYuR, VT3-1, and 1Kh12N2VMF alloys leads to a considerable improvement of the mechanical properties. This improvement results from the fragmentation of particles of the strengthening phases, a

1. At the normally used rates of heating the α»γ transformation occurs in the aged martensitic matrix, which together with phase work hardening from the α»γ transformation causes the formation of austenite with an increased hardness. With an in

Steel 1, with σb = 260−280 kg/mm2, retains high local plasticity even in notched samples, but has a high crack sensitivity. Steel 2, with σb = 235−245 kg/mm2, has a relatively low crack sensitivity under static load. Additional studies of the s
