Regularities in The disordered atomic structure of rapidly quenched amorphous cobalt-based alloys

Research presents regularities investigation in the atomic structure of amorphous rapidly quenched Co58Ni10Fe5Si11B16 at.% alloys. The alloys were quenched on a copper wheel with a linear surface velocity from 22 to 38 m/s. We found nonlinear dependence of local atomic ordering from linear velocity of cooling wheel. Average lateral density of ordered atomic clusters of 5 nm size changes from 4% to 8%. This approach can be used to determine the best technological parameters for preparing amorphous metallic alloy with metastable structure.
