The displacive-diffusive formation of single-tilt surface reliefs produced by precipitation of γ lamellae in Ti48Al2Cr2Nb alloy

Surface reliefs produced by the precipitation of γ lamellae are of single-tilt type, and terraces and step risers can be observed on the surface relief. The height of the surface relief is closely related to the width of the γ lamella and each surface relief of regular γ lamellae consists of γ lamella and accommodated matrix. This accommodation prohibits the ordering process in the related matrix near the specimen surface.556
