Abstract

We have used rapid e-beam heating and quenching to study metastable transitions between allotropic phases in Mn and to determine relative rates of transformation between the allotropes. The equilibrium α ⇉ β transition at 720 °C is bypassed and the metastable α ⇉ γ transition is observed to occur at a temperature (880 ± 30 °C) near that predicted thermodynamically (864 °C).
