dc.description.abstract | This paper summarizes a mathematical model for the industrial heating and cooling
processes of a steel workpiece corresponding to the steering rack of an automobile. The general
purpose of the heat treatment process is to create the necessary hardness on critical parts of the
workpiece. Hardening consists of heating the workpiece up to a threshold temperature followed by a
rapid cooling such as aquaquenching. The high hardness is due to the steel phase transformation
accompanying the rapid cooling resulting in non-equilibrium phases, one of which is the hard microconstituent
of steel, namely martensite. The mathematical model describes both processes, heating
and cooling. During the first one, heat is produced by Joule’s effect from a very high alternating current
passing through the rack. This situation is governed by a set of coupled PDEs/ODEs involving
the electric potential, the magnetic vector potential, the temperature, the austenite transformation,
the stresses and the displacement field. Once the workpiece has reached the desired temperature,
the current is switched off an the cooling stage starts by aquaquenching. In this case, the governing
equations involve the temperature, the austenite and martensite phase fractions, the stresses and
the displacement field. This mathematical model has been solved by the FEM and 2D numerical
simulations are discussed along the paper. | es |
