    Notes: Conclusions 1. The formation of the binary carbide (Ti, Ni)6C in steels Kh18N10T and Kh18N12T depends on their chemical composition and treatment. 2. The precipitation of the binary carbide occurs in steels with Ti/C〉5 and 0.07–0.12% C. 3. Cold plastic deformation and quenching from a low temperature favor precipitation of the binary carbide during aging at 650°. Hot plastic deformation has not effect on the precipitation of (Ti, Ni)6C.

    Notes: Conclusions 1. The stability of supercooled austenite in complex alloy Cr−Mo−V steels during decomposition by the pearlitic mechanism is greatly affected by the carbon content of the solid solution (from 0.45 to 0.90%). 2. With high supersaturation and low diffusional mobility of carbon atoms, a ferritecarbide mixture is formed with the particles in the shape of dendrites. With somewhat less supersaturation of austenite and higher diffusional mobility of carbon atoms one observed simultaneous growth of several dendrites from one center and linking. This results in the formation of pearlite cells in the shape of globules consisting of several fragments — growing dendrites. When the decomposition temperature is raised to 650–700°C and with increasing holding times, the dendrites are transformed to globules.

    Notes: Conclusions 1. Plastic deformation substantially accelerates precipitation of σ phase and carbides TiC and (Ti, Ni)6C in steel 12Kh18N10T, the intensifying effect decreasing notably when the rolling temperature is raised from 20 to 1000°. 2. Plastic deformation substantially reduces the fracture toughness of steel 12Kh18N10T after prolonged holding at 650°. The fracture toughness decreases least after high-temperature and cold deformation with 15% reduction. 3. The effect of preliminary polygonization annealing on the properties of steel 12Kh18N10T is retained during subsequent heating to 650° for as long as 500 h. 4. The structure resulting from high-temperature deformation is the most stable during prolonged heating at 650°.

    Notes: Conclusions 1. High-temperature mechanicothermal treatment at 900–1100\dgC with 12–15 and 25–28% reduction notably increases the strength characteristics of steel Kh18N10T but reduces the plasticity only slightly. The strength increases as the rolling temperature decreases and the degree of deformation increases. 2. The thermal stability of the hardening resulting from HTMTT under conditions completely preventing recrystallization depends very little on the rolling temperature but mainly on the degree of reduction. The thermal stability is highest after 12–15% reduction at 900–1000°C. 3. The partial development of recrystallization during high-temperature deformation sharply reduces the thermal stability of the cold hardening resulting from HTMTT.

    Notes: Conclusions 1. Considerable strengthening of weakly precipitation-hardening alloys of the Al−Mg−Si system can be obtained by LTMTT (ε=95%), leading to the development of texture and intensive zone decomposition of the solid solution during subsequent aging at 140°. 2. The increase in strength due to LTMTT can be increased by deformation in two stages with approximately equal deformation in each stage and totalling 95%, alternating with aging at 140°.
