Abstract
The structures of α' and ε martensite in 18/8 and 18/12 steels, observed using electron microscopy techniques are reported. Structural changes associated with the reverse transformations of these phases to austenite, γ, on heating, together with compositional variations are presented and mechanisms of both the direct and reverse transformations are discussed.
