Characterization of Cu-Al-Ni melt-spun ribbons using a focussed ion beam (FIB) = Karakterizacija hitrostrjenih trakov zlitine Cu-Al-Ni z uporabo fokusiranega ionskega curkaZupanič, Franc ...This work investigates the possibilities for applying a focussed ion beam (FIB) for the metallographic preparation and characterization of Cu-Al-Ni melt-spun ribbons. Two alloys were selected for ... this reason: CuAl13Ni4 and CuAl15Ni4. The microstructure of the first alloy was fully martensitic and the microstructure of the second consisted of two phases: martensite and ▫$\gamma_2$▫. It was discovered that with FIB-etching the microstructures of both alloys can be clearly revealed on polished cross-sections of the melt-spun ribbons, as well as on their wheel-side and air-side surfaces. However, better results were obtained when the etched surface was smoother, and finer details were visible when using smaller ion currents. In addition, a study was made into the influence of platinum deposition on the quality of 3D-cross sections. It was found that Pt-deposition is necessary when the edge of the trench should be straight and sharp, and the surface of the 3D cross-section smooth. However, in this case, the microstructure of the ribbons free surface cannot be seen.Source: RMZ - Materials and geoenvironment : periodical for mining, metallurgy and geology = RMZ - Materiali in geookolje : revija za rudarstvo, metalurgijo in geologijo. - ISSN 1408-7073 (Letn. 54, št. 3, dec. 2007, str. 319-329)Type of material - article, component partPublish date - 2007Language - englishCOBISS.SI-ID - 12060182
