A COMPUTATIONAL ANALYSIS OF THERMAL RESIDUAL STRESS DURING MAGNETIC QUENCHING
In this paper, based on the analysis of coupling action of temperature, phase transformation, magnetic field and stress, the phase transformation condition and equation related to material properties are discussed, a new constitutive equation considering effects of phase transformation and magnetic field is proposed and solved by means of Finite Element Method (F.E.M). The thermal residual stress is obtained and the influencing factors on the thermal stress of magnetic field are analysed and discussed.
