Study of the Mechanical Properties of Single-Layered and Bilayered CoCrFeSi Ribbons Using Quasistatic and Dynamic Nanoindentation Tests

Abstract:

In this work we have studied local mechanical properties of CoCrFeSiB ribbons prepared by planar flow casting (PFC). Recently improved PFC technology enabled us to use two melts simultaneously and to prepare a bilayered Co₆₉Fe₂Cr₇Si₈B₁₄/Co₅₉Fe₁₂Cr₇Si₈B₁₄ ribbon with a good homogeneity of the layers and well defined interface. Single-layered ribbons of the two compositions above were prepared as well. The microstructure and the composition profiles were studied by means of analytical electron microscopy. Nanoindentation tests were carried out on the cross sections of the bilayered ribbon as well as of single-layered ribbons. The in-situ SPM imaging was used in order to achieve nanometer precision positioning of the indents and to get information about the surface topography before and after the tests.
