Thermomechanical treatment of 2014 aluminium alloy

Materials Science and Technology, 1988
AbstractThe effect of thermomechanical treatment on the flow stress, fracture strain, structure, and precipitation behaviour of commercial grade 2014 aluminium alloy has been investigated. Specimens in the supersaturated and aged conditions were plastically deformed in torsion tests in the temperature range 293–493 k and strain rate range 2·8 ×10−3−2·5

Thermomechanical treatments of a 1050 pearlite steel

Metallurgical Transactions A, 1983
A study of the microstructures and mechanical properties of thermomechanically treated 1050 steel has been carried out. The materials were first transformed to fine and coarse lamellar pearlite structures. These samples were reduced 75 pct in thickness by cold rolling, then heat treated at 780 °C (up-quenching) or 650 °C (annealing) for different ...

Thermomechanical treatment of titanium alloys

Metal Science and Heat Treatment of Metals, 1962
1. The best results from TMT on alloy VTZ-1 are attained after deformation at 850° with subsequent tempering. 2. The mechanical properties of titanium alloys subjected to TMT, regardless of the operating conditions, are higher than if these alloys are subjected to heat treatment only, without deformation.

Thermomechanical treatment of boring chisels

Metal Science and Heat Treatment, 1966
1. 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.

Production of isotropic materials by thermomechanical treatment

Soviet Materials Science, 1968
The 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, 1963
1. 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 ...

Subcritical thermomechanical treatments of eutectoid steel

Metal Science, 1983
AbstractThe 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, 2015
The 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 ...

Preliminary thermomechanical treatment of D6AC steel

Metallurgical Transactions, 1970
The effect of preliminary thermomechanical treatment on the strength, elongation, hardness, X-ray line broadening, and prior austenite grain size of D6AC steel has been investigated. In this type of treatment the deformation is performed prior to austenitizing, and rapid rate heating to the austenitizing temperature must be used.

Effect of thermomechanical treatment on the corrosion of AA5083

Corrosion Science, 2010
Abstract 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
