Peculiarities of deformation behavior of magnetic parameters of a maraging steel characterized by different degrees of precipitation hardening

The deformation behavior of the magnetic characteristics of maraging steel 03X11H10M2T (there exists Pi 678), which is subjected to hardening followed by aging at temperatures of 400-580 degrees C, is studied. Nonmonotonic variations of the coercive force in the elastic region are shown to result from two factors: the positive magnetoelastic effect and the presence of second-phase particles whose geometric size increases substantially with increasing aging temperature. Two-parameter nomograms are constructed that allow the current states of loaded structural elements made of the steel under study to be estimated from their magnetic characteristics.
