Paper Title:
Residual Life Assessment for Ferromagnetic Components Based on Metal Magnetic Memory Technology
  Abstract

The fatigue crack growth experiment was carried out at room temperature for the standard SEB(3) specimens of 40Cr steel, the distribution of the surface magnetic field of the specimen under same load and different cycle numbers (N) was studied. By analyzing relations between the magnetic signals and the crack propagation life, a new damage parameter model has been established by magnetic signals. According to this model, we can evaluate the residual life of ferromagnetic components excellently. This belong to basic research on early damage inspecting and residual life assessment for ferromagnetic materials, it confirmed that residual life assessment and safety estimating for ferromagnetic components based on metal magnetic memory technology is feasible.
