Prediction of the hardness of X12m using Barkhausen noise and component analysis methods

•A novel feature descriptor designed for BN signal of material hardness is proposed.•A new algorithm m-SFA based on multi-order SSFA signals is generated.•Discriminant incoherent component analysis was firstly employed in NDT. Barkhausen noise (BN) generated by the stochastic movements of domain wal...
