Abstract

The interface reactions in (1 nm Fe/x nm W) and (2 nm Fe/x mn W) multilayers (x = 1, 2, 5 and 7) with 5 or 10 periods in as-deposited state and under KrF laser irradiation with fluences, F 0.05-0.25 J cm(-2) and 1 or 10 pulses were studied by X-ray diffraction (XRD), grazing incidence (GI) XRD, X-ray reflectivity, GI X-ray diffuse scattering and cross-section transmission electron microscopy (XTEM). Structurally coherent layers along the [110] direction with bcc symmetry were found in as-deposited and irradiated samples. This coherency is affected by the lateral waviness of the interfaces. The layered structure persists up to F 0.25 J cm(-2) and 10 pulses. Under the laser treatment, both the interface roughness and mixing increase with increasing deposited energy and promoted bcc W grain growth is observed.
