抄録

With an electron-microscope, observation was made on the fine lamellae (spacing=150∼300 Å) in the martensite of Kovar using replicas. The results were as follows: (1) Lamellae are hardly seen in the surface relief (the surface is electrolytically polished before transformation), but they are clearly revealed by light etching of that surface. Their form and density are nearly the same as in the case of the surface relief of Fe-Ni alloys. (2) They look to consist of parallel ridges somewhat different from the ordinary deformation slips. They are distributed more densely and more uniformly all over the martensite plate than in the latter case. (3) The appearance of these fine parallel lamellae supports the idea that transformation slip with a fine spacing occurs in the martensite during the transformation.
