1. Even elongation, determining the ability of metals to change their shape, depends mainly on the rate of reduction of the relative hardening with increasing strain. For martensitic steels, including high-carbon steels, which are not inferior to aus

1. Steel VNS-2 heat-treated by an optimum mode has high fracture toughness. 2. Deviations from the optimum mode in hot work and heat treatment may lead to substantial embrittlement of the steel. 3. A content of about 10% residual austenite in the ste

1. The stability of austenite in stainless steels, determining the rate of the γ → α transformation at different deformation temperatures, can be determined fairly accurately by calculating the chromium equivalent of martensite formation CreqvM f

1. A thermomechanical treatment with a 90% reduction below the recrystallization temperature of constructional steels with a broad range of stable austenite can develop σb=280 to 300 kg/sq.mm at δ5=6% which by far exceeds the properties of these st

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

‘Transitional’ steels have an unusual combination of mechanical properties. They may have a low yield stress (20–40 kg/sq. mm=28, 400–56, 900 psi) and a high tensile strength (100–200 kg/sq mm=142, 000–284, 000 psi). The mechanical proper

The commercially used corrosion-resistant steel 0Kh20N6MD2T can be hardened by aging, without distortion, to a yield point of at least 60kg/mm2 and ultimate strength of at least 80 kg/mm2 with reduction in section of at least 50%, specific elongation

The main reasons for the low plasticity and ductility of maraging steel 00N18K9M5T in large sections are the coarse-grained structure resulting from heating for hot working and the precipitation of carbides or titanium carbonitrides in the form of a
