Anaerobic treatment of hemp thermomechanical pulping wastewater
Water Research, 1998Abstract Biological treatment is an indispensable instrument for water management of non-wood pulp mills, either as internal measure or end of pipe. In this paper, anaerobic treatment of wastewaters derived from the thermomechanical pulping (TMP) of hemp (Cannabis sativa L.) is described.

Preliminary thermomechanical treatment of pipes
Metal Science and Heat Treatment, 19661. Thermomechanical treatment combined with cold rolling (PTMT) of pipes made of 30KhGSA steel increases the strength by 30–50 kg/mm2 and the yield point by 20–35 kg/mm2 with tempering at 100–400°C. 2. Neither the size nor the shape of the austenitic grains is the determining factor in hardening the steel by thermomechanical treatment.

Thermomechanical treatment of 2014 aluminium alloy
Materials Science and Technology, 1988AbstractThe 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 treatment of R18 steel
Metal Science and Heat Treatment, 19681. After HTTMT of high-speed steel R18 by the optimum method the bending strength is 440 kg/mm2; after the standard treatment is 250 kg/mm2. 2. Reduction of the deformation temperature leads to impoverishment of the solid solution in carbon and alloying elements, promotes the precipitation and coalescence of carbides, and sharply reduces

Thermomechanical treatment of structural carbon steel
Metal Science and Heat Treatment, 19651. High temperature thermomechanical treatment of medium carbon structural steels subjected to plastic deformation by torsion during this treatment results in the best mechanical properties, the highest corrosion resistance and the highest corrosion fatigue resistance when the degree of deformation during the treatment is of a given value.

Thermomechanical Treatment Using Substructural Strengthening
Metal Science Journal, 1973AbstractThe present position of theory and practice concerning methods of increasing the strength of ferrous and nonferrous alloys by thermomechanical and mechanical/thermal treatment is described. Special attention is given to methods using substructural strengthening as they allow combinations of high strength and good ductility to be obtained.

Thermomechanical treatment of ball-bearing steel
Metal Science and Heat Treatment of Metals, 1962The effect of the newly developed thermomechanical treatment on Soviet ball-bearing steels was investigated, using both cylindrical and flat specimens. The test specimens were exposed to annealing temperatures ranging up to 550 deg C, followed by cooling in air.

Thermomechanical Treatment of Metal Composite Fractions
Chemie Ingenieur Technik, 2015AbstractThe investigation focuses on shredder light fractions, electrical waste, and metal concentrates from landfills that can be treated mechanically only with difficulty. The fractions were input to a combined thermomechanical treatment to procure a high degree of composite component separation.

Thermomechanical treatment of titanium alloys
Metal Science and Heat Treatment of Metals, 19621. 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.

Hardenability of steel with thermomechanical treatment
Metal Science and Heat Treatment, 19741. Plastic deformation of austenite during HTTMT shifts the isothermal transformation curves to the left and reduces the hardenability of steel. 2. A method was proposed for plotting a calibration curve in order to determine the relationship between the hardenability of steel after HTTMT and after standard quenching. 3.
