説明
The relation between crack nucleation and stress-induced martensitic transformation in retained massive austenite (RM-γ) of austempered ductile iron (ADI) was examined in detail by means of tensile deformation tests and SEM observations for an ADI material. SEM observations revealed that cracks were not nucleated on boundaries between spheroidal graphites and matrix, but in RM-γ. Surface relieves due to stress-induced martensitic transformation were observed in RM-γ near the cracks. Surface relieves were also observed in RM-γ in which cracks were not nucleated. Consequently, the cracks were concluded to be nucleated in RM-γ subject to stress-induced martensitic transformation.
