Measurement of the Hardness of Medium Carbon Steel Using the Magnetic Mixing-Frequency Technique
IEEE Transactions on Magnetics(2018)
摘要
The mixing-frequency method is an effective technique to measure the magnetic nonlinearity of medium carbon steel. In this paper, the magnetic mixing-frequency method was investigated to evaluate the hardness of medium carbon steels. The magnetic nonlinear factors related to the bispectral amplitudes at sum frequency, different frequencies, and fundamental frequencies in the measured signal are pr...
