1. Heating the KhN56MBYuD alloy before quenching at 980–1180°C for 0.5–2 h helps dissolve the eutectic, increase the volume fraction of the sulfide (compared to the as-received state), coagulate the carbonitride, and significantly grow the grain

1. The cooling capacity of UZSP-1 polymeric quenching medium is determined by the molecular mass (MM) of the copolymer. 2. With concentrations of more than 1.5% for the UZSP-1 solutions, their cooling capacity is virtually constant for a constant MM

1. The size of the austenite grain of 20Kh steel depends after TCT on the cooling rate from the temperature of the upper cycle (tu.li). 2. TCT with slow heating (vk=5–10 K/min) and cooling from tu.li at rates 10–100 K/min makes possible the reduc

1. With an increase in steel alloying there is an increase in the optimum carbon content in the surface film of diffusion layers, and as a consequence there is an increase in the content of excess phases which reduce wear. After TCT steel 16Kh2N3MFBA

1. The stability of supercooled austenite in the pearlitic region does not depend on the melting procedure; in the intermediate region the stability is highest for the ESR method. 2. The changes observed in the kinetics of the decomposition of superc

1. Use of the computer to develop steel compositions is expedient only when methods of mathematical design are employed, i.e., in conducting "active" experiments. 2. Use of methods of mathematical design and the computer made it possible to develop a
