Production of isotropic materials by thermomechanical treatment
Soviet Materials Science, 1968The general principles of thermomechanical treatment for ensuring isotropy of mechanical properties are discussed. The deformation conditions of isotropy are formulated, and an expression is derived for estimating the intensity of plastic deformation during the treatment which may consist of several cycles.

Effect of thermomechanical treatment on fine structure
Metal Science and Heat Treatment, 19631. Thermomechanical treatment improves the mechanical characteristics because of a) decrease of the size of grains of the original γ-phase in steel and the grains of the β-phase in titanium alloys as well as the size of the martensite platelets; b) the change in the ratio of the phase components (for average values of plastic deformation the ...

Thermomechanical treatment of boring chisels
Metal Science and Heat Treatment, 19661. Thermomechanical treatment increases the working life of chisels by 20–30% in cutting quenched steel. 2. The optimum deformation temperature of the head of the chisel is 500° C. Cooling below 500°C decreases the ductility of the metal and leads to the formation of cracks during deformation. 3.

Subcritical thermomechanical treatments of eutectoid steel
Metal Science, 1983AbstractThe kinetics of annealing of eutectoid steel which was 75% cold rolled and then annealed at temperatures of 400, 500, and 600°C have been examined using measurements of microhardness, X-ray textures and line broadening, scanning and transmission electron microscopy, and positron annihilation.

Thermomechanical Treatment of Aging Aluminum Alloys
Metal Science and Heat Treatment, 2015The mechanical properties, corrosion resistance and fracture behavior of precipitation-hardening aluminum alloys of different alloying systems are studied after a thermomechanical treatment with deformation in a wide temperature range. Application of deformation at the temperature of optimum aging in the thermomechanical treatment is shown to have a ...

Effect of thermomechanical treatment on the corrosion of AA5083
Corrosion Science, 2010Abstract Corrosion resistance degradation induced by the presence of β-phase (Al3Mg2) limits the performance of aluminum alloy 5083 for some critical applications. The effect of thermomechanical treatment on the corrosion of AA5083 is presented in this paper. The samples subjected to the thermomechanical treatment showed superior corrosion resistance
