The mechanical properties of metals can be changed to a remarkable extent by subjecting them to heat treatment. Steel is unique in its ability to exist both as a soft material which can be easily machined, and after heat treatment as a hard material out of which metal cutting tools can be made.

Heat treatment of steel with induction heating
Metal Science and Heat Treatment, 1967Induction hardening makes it possible to obtain a favorable combination of properties, high static strength, fatigue strength, and contact strength with minimal alloying of the steel.

Abstract A method of annealing uranium which produces a fine-grained, quasi-isotropic structure is described. It is shown that the strength of uranium can be improved by annealing from the β- and γ-phases, and the influence of annealing on the fine and coarse grain structure, depending on the chemical composition, is considered.

1. Low-temperature heat treatment with the new device relieves stresses in weld seams. 2. The length of the heat treatment of weldments when using this device is cut down by a factor of 25–30 compared with treatment in a furnace. By using this device one of the plants that ordered it has been able to save 7000 rubles.

Tribology International, 1978
Abstract This paper reviews recent developments in the application of high power lasers to materials processing technology. The use of fine beams of laser energy to modify the surface properties of metallic materials is described in detail with specific emphasis on transformation hardening, surface alloying, and laser glazing.

Metallurgical Transactions, 1971
Multistage heat treatments have been used to clarify transformation mechanisms and to provide a basis for reducing heat treating time in commercial practice and/or obtaining improved properties. The influence of stepped transformation on the kinetics of the bainite reaction is examined and the results suggest means for improving the hardenability of ...

Heat treatment makes it possible to considerably improve the strength and reducibility of the sinter, to raise the temperature of the start of softening, and to reduce the content of sulfur in the sinter. The optimum temperature of heat treatment is equal to 1050–1100°C.

Heat-based processes have been used for centuries for food preservation and still remain the most widely used preservation technique in food manufacturing. However, thermal processing treatments are not as efficacious in the destruction of pathogenic microorganisms at low water activities compared to moist environments.
