Abstract
⺠We analyze the nonlinear Lamb wave for ageing behavior study in Fe-Cr-Ni steels. ⺠Nonlinear Lamb wave increases with formation of precipitate at early ageing time. ⺠It keeps as a plateau with precipitate dynamic balance for a long-term ageing. ⺠It reduces at final ageing time for precipitate coarsening and microvoids initiation. ⺠Variation of nonlinear Lamb wave follows same trend as that of hardness in samples.
