Abstract

Interphase boundary structures were compared between lath-shaped bainitic ferrite in Fe-0.6C-2Si-1Mn and lath martensite in Fe-20Ni-5.5Mn. Both laths exhibit the macroscopic habit plane scattered around (1 2 1)γ which contains monoatomic steps with the (1 1 1)γ∥(0 1 1)α terrace (transformation dislocations/structural ledges). Similar accommodation dislocations, with pure-screw characters on (1 1 1)γ∥(0 1 1)α, were observed in both cases.
