“…[1][2][3][4][5][6][7] The theory and modeling of transformation kinetics under stress is nowadays essential in materials science and processing, however, the reported work on such topics is quite few, especially in the area of diffusional transformation. It has been shown that the nucleation rate of the pearlite transformation increases strongly with the applied stress.…”

“…4) and of mechanics on metallurgy (arrow no. 6) as second-order e ects, since it has been observed that for such steels the in uence of the stress state on the transformation diagrams is small [4,5]. This assumption enables us to solve the thermometallurgical problem independently of the mechanical one.…”

A coupled gas-dynamical and thermo-mechanical model for simulation of the gas flow, gas and specimen temperature, phase, stress, strain, and displacement transient-fields during quenching of cutting discs and shafts of steel is introduced. The material properties (e. g. density, conductivity, heat capacity, hardness) are obtained by homogenization procedures. The material behaviour is described as an extension of the classical J 2 -plasticity theory with the extension of temperature and phase fraction dependent yield criteria. The coupling effects such as dissipation, phase transformation enthalpy, and transformation induced plasticity (TRIP) are considered. Simulations were carried out for cutting discs of knives, and for shafts made of steel SAE 52100 with varying diameter. For the validation of the simulations, these work pieces were heated in a roller hearth kiln up to 850 C, and than quenched in a field of nozzles in which the heat transfer coefficient was known and could be locally adjusted by the volume flow of each nozzle. The phase fractions, surface hardness, distortion, and residual stresses were measured. The simulated and measured results fit quite well. According to optimization-simulations the shafts were quenched with a certain heat transfer coefficient distribution. The bigger diameter parts of the shaft were more intensively quenched by an increased gas flow so that the hardness profiles were equalized and the residual stresses at the edges were significantly reduced.Keywords
