Abstract
The structure of amorphous Ti50Ni25Cu25 alloy is investigated upon megaplastic deformation in a Bridgman chamber at room temperature. The dependences of average and local fractions of the crystalline phase along a sample’s radius on deformation are obtained. Radial distribution functions that allow calculation of the interatomic distances and coordinate numbers in several coordinate shells of investigated sample are found. It is concluded that the amorphous state in a Ti50Ni25Cu25 system fabricated by melt quenching is virtually the same as the one that arises through deformation-driven amorphization at room temperature in a Bridgman chamber.
