Since diffusion based high-temperature synthesis occurs without the presence of air, efforts have focused on investigating the understanding of the fundamental reaction processes and characteristics. The aim of this study is to expose the reactive multilayers to extrinsic induced tensile stress so that the self-propagating synthesis can proceed under these conditions. Further, the properties during and after the reaction will be investigated. Multilayers deposited by sputtering on Kapton® substrates with different bilayer- and total thicknesses as well as commercial Nanofoils® with thicknesses of 40 µm and 60 µm were used as samples. The investigations focused on the propagation velocity measured with a high-speed camera, the temperature regime determined with a high-speed pyrometer, and the formed phases after the synthesis examined via X-ray diffraction. The gained results of this study reveal important insights for the application of the reactive Al/Ni multilayer system in terms of stability or reliability related to propagation front velocity, maximum temperature and formed phases under induced external tensile stresses. article Glaser, Marcus Author aut (DE-588)1304373185 Vardo, Emina Author aut (DE-588)1299766323 Sauni Camposano, Yesenia Haydee Author aut (DE-588)1299765955 Jaekel, Konrad Author aut (DE-588)1299762093 Bergmann, Jean Pierre 1972 - Author aut (DE-588)137074212 Schaaf, Peter 1963 - Author aut (DE-588)137351313 Camposano, Yesenia Haydee Sauni Author aut Technische Universität Ilmenau Fakultät für Elektrotechnik und Informationstechnik host institution his 202300000580024915 58:24<10085 Technische Universität Ilmenau, Universitätsbibliothek Journal of materials science 1573-4803 dbt_mods_00051670 1.1966 - https://www.db-thueringen.de/receive/dbt_mods_00062405 object in context https://www.db-thueringen.de/servlets/MCRFileNodeServlet/dbt_derivate_00064726/1573-4803_58_2023_10085-10095.pdf raw object https://www.db-thueringen.de/rsc/thumbnail/dbt_mods_00062405.png preview http://uri.gbv.de/document/gvk:ppn:1851586571 uri
