A study on residual stresses in surface hardening by high frequency induction heating

Experimental investigation on the mechanical behavior of high-frequency induction-hardened mild carbon, SPS5 steel

“…Among them, the highfrequency induction hardening treatment can control and change only some of the surface layer in comparison with most of other heat treatment methods and therefore its usability is very high. Accordingly, a number of studies have been carried out to investigate the mechanical properties and structural changes of materials surface-treated by induction hardening [1][2][3][4]. * Ahn et al [5] examined changes in the mechanical properties of low alloy steel due to induction hardening treatment from structural aspects.…”

Effect of electric contact surface treatment on microstructure and wear behaviour of ductile iron

“…1 The main techniques used in the surface modification are laser, [2][3][4][5] electron beam 6,7 and induction. [8][9][10] All the techniques have a common feature: the treated surface is subjected to a rapid heating followed by a similarly rapid cooling. However, a factor restricting the wider use of these techniques in manufacturing is the difficulty and cost in handling either lasers or electron beams.…”

A numerical algorithm for the full coupling of mechanical deformation, thermal deformation and phase transformation in surface grinding

“…Okamura et al (1989) developed a method using the ®nite element method to analyze processes involving phase transformation for analyzing the distortion of oil-quenched gear rings. Kim et al (1992) analyzed the transient heat¯ow and thermal stress during surface hardening by a modi®ed two-dimensional ®nite element model. Nakasaki et al (1997) developed and applied the ®nite element computer package`HEARTS' based on the metallo-thermo-mechanics to the simulation of the quenching process of a carbon steel (S45C) by pulsed YAG laser, which allowed them to evaluate the coupled effects of phase transformation, temperature and stress.…”
