The Influence of High Magnetic Field on the Stability of CryoECAPed 1050 Alloy

The evolutions of mechanical properties and microstructure of cryoECAPed 1050 alloy annealed at various temperatures from 150°C to 400°C for 1h with and without high magnetic field (HMF) were investigated by hardness test and electron back scattering diffraction pattern (EBSD) analysis. The abnormal grain growth happens in sample annealing at 400°C without a field. With the application of high magnetic field, the formation of the HABs is suppressed, the grain size distribution is homogeneous and no abnormal grain growth occurs.
