Computer simulation of induction hardening
Journal of Materials Processing Technology, 2004The computer simulation of electromagnetic, thermodynamic and microstructural transformations in treated work-piece is usually recommended for the exact definition of working parameters in process planning of the induction hardening processes. A special simulation program has been developed for the axially symmetric work-pieces.

<div class="section abstract"><div class="htmlview paragraph">INDUCTION heating, the authors show, has been successfully applied to the hardening of many types of gears. Over a million transmission gears have been produced with its aid and thousands of induction-hardened final-drive gears and pinions are giving satisfactory field service ...

Analysis of Induction Hardened Cylinders
Heat Treating Conference, 2023Abstract Induction hardening is used to harden small cylinders of SAE 1074 steel. Parts were quenched with a high concentration of a polyalkylene glycol (PAG) type quenchant. Soft spots were found on a small percentage of the parts. These soft spots were consistently at one location about 2/3 from the bottom of the part. These soft spots

Kinetics of hardened layer formation with induction hardening
Metal Science and Heat Treatment, 2010The kinetics of martensitic transformation of roll steels with induction heating by a current of industrial frequency are studied. It is shown that martensitic transformation proceeds autocatalytically. The time dependence of the amount of martensite with decomposition of supercooled austenite is established.

Measurement of Induction-Hardening Depth
2003In case of inhomogeneous materials, the resonance frequency is governed by the elastic constants and density at the positions of maximum stress and amplitude, respectively, which locate in the medium, depending on the individual resonant mode. Different resonant modes provide the information on the elastic property at different positions, and the ...

Steels with controlled hardenability for induction hardening
Metal Science and Heat Treatment, 1980Steels of the CH and LH type developed in the Soviet Union permit the use of a new method of induction hardening — bulk-surface hardening — and efficient utilization of the high-strength conditions (σb = 230–250 kgf/mm2). These steels make it possible to improve the structural strength, operating characteristics, service life, and reliability of ...

Abstract Induction heating, in most applications, is used to selectively heat only a portion of the workpiece that requires treatment. This chapter covers the basic principles, features, and metallurgical aspects of induction heating. The discussion includes the conditions required for induction heating and quenching, the use of magnetic

Breakthrough in Induction Hardening Shafts
Heat Treating Conference, 2015Abstract This presentation reviews selected innovations related to induction hardening of various automotive powertrain transmission and engine components, including but not limited to induction surface hardening of complex geometry shafts. Thanks to several innovative designs (patented and patent pending), important goals were achieved.

Abstract Some gears may need to be hardened only at the surface without altering the chemical composition of the surface layers. Induction hardening may be a suitable processing choice in these cases. This chapter provides information on the wide variety of materials that can be induction hardened and on process details involved in ...

Abstract Induction and flame hardening are methods of hardening the surfaces of components, usually in selected areas, by the short-time application of high-intensity heating followed by quenching. These processes are used when gear teeth require high hardness, but size or configuration does not lend itself to carburizing and quenching ...
