Abstract

A body-centered tetragonal (bet) twin martensite has been found in Co ₃₉Ni₃₃Al₂₈ ferromagnetic shape memory alloy by transmission electron microscope (TEM) observation. The twin lamellae have ∑ = 25 (011̄) twin boundaries and slip system [011]//(011̄). Periodic appearance of the twin lamellae resulted in a modulated structure with a repeat periodicity of 56d011 perpendicular to the twin interface. The twinning mechanism during martensite transformation is discussed briefly.
