Abstract
ⶠCompressive elastic stresses up to 250 MPa are applied in continuous cooling. ⶠUsing the thermodynamic data and maximum value of the mechanical driving force the predicted increase in Ms (â¼0.1 K/MPa) is in agreement with experiment ⶠAustenite was deformed plastically at different temperatures (800 °C-1100 °C). ⶠHigh deformation temperature (i.e. 1100 °C) as well as low plastic strain (i.e. Éave â¼Â 30%) do not affect martensite transformation noticeably, whereas lower deformation temperature (e.g. 900 °C) and large plastic strain (i.e. Éave â¼Â 70%) retards martensite transformation. ⶠThe theory of mechanical stabilization predicts the depression of Ms.
