Аннотация
© 2021, Pleiades Publishing, Ltd.Abstract: Amorphous-crystalline alloy of the TiNi–TiCu quasi-binary system with 25 at.% copper content is prepared in the form of thin ribbons by rapid quenching from a liquid state. Completely amorphous ribbons are obtained using electrochemical polishing. It is shown that the crystal structure prepared by high-speed electropulsing heat treatment differ significantly from that prepared by isothermal heat treatment. The initial ribbon crystallizes as column-like crystals growing from both surfaces of the ribbon and as large lens-like crystals in the volume of the ribbon. The structure of column-like crystals reproduces the morphology and texture of the original crystalline layer. Reducing the electropulsing time to 1 ms increases the fraction of column-like crystals while their height increases and the width decreases. After the amorphous ribbon is crystallized, the structures of column-like crystals on both surfaces have similar crystallographic orientations.
