Thin foils for combined STEM and SEM experiments were prepared by electrolytic twin-jet polishing. They were in-situ heated in a TEM heating stage and observed at 200 kV in the JEOL JEM 2200FS electron microscope equipped with STEM HAADF and BF detectors and SEM BSE and SE detectors working both in composition and topographic modes. The resulting structures were combined with EDS mapping performed directly in the heating holder. Dissolution and transformation of Cu- and Fe-rich particles occur above 500 °C. EDS maps acquired on the foil cooled down to room temperature show that Cu and Fe are both still present in newly formed particles, most likely indicating the presence of the Al7Cu2Fe phase.","lang":"eng"}],"publication":"METAL 2022 Conference Proeedings","main_file_link":[{"open_access":"1","url":"https://www.confer.cz/metal/2022/4438-homogenization-of-twin-roll-cast-al-li-based-alloy-studied-by-in-situ-electron-microscopy"}],"conference":{"end_date":"2022-05-19","location":"Brno","name":"Metal 2022","start_date":"2022-05-18"},"doi":"10.37904/metal.2022.4438","oa":"1","date_updated":"2023-01-12T09:44:17Z","author":[{"full_name":"CIESLAR, Miroslav","last_name":"CIESLAR","first_name":"Miroslav"},{"last_name":"KŘIVSKÁ","full_name":"KŘIVSKÁ, Barbora","first_name":"Barbora"},{"full_name":"KRÁLÍK, Rostislav","last_name":"KRÁLÍK","first_name":"Rostislav"},{"full_name":"BAJTOŠOVÁ, Lucia","last_name":"BAJTOŠOVÁ","first_name":"Lucia"},{"first_name":"Olexandr","full_name":"Grydin, Olexandr","id":"43822","last_name":"Grydin"},{"full_name":"STOLBCHENKO, Mykhailo","last_name":"STOLBCHENKO","first_name":"Mykhailo"},{"last_name":"Schaper","id":"43720","full_name":"Schaper, Mirko","first_name":"Mirko"}],"citation":{"chicago":"CIESLAR, Miroslav, Barbora KŘIVSKÁ, Rostislav KRÁLÍK, Lucia BAJTOŠOVÁ, Olexandr Grydin, Mykhailo STOLBCHENKO, and Mirko Schaper. “HOMOGENIZATION OF TWIN-ROLL CAST Al-Li-BASED ALLOY STUDIED BY IN-SITU ELECTRON MICROSCOPY.” In <i>METAL 2022 Conference Proeedings</i>.

Investigated micro FE-simulations show that the matrix of UD composites exhibits different average plastic behaviour, named as average asymmetric matrix plasticity (AAMP), when the composite behaves different under shear, longitudinal and transverse loadings. In this study, a non-linear mean-field debonding model (NMFDM) combining a mean-field model and a fibre–matrix interface debonding model, is developed to simulate UD composites under consideration of AAMP, fibre–matrix interface damage and progressive failure. AAMP is considered by using so-called stress mode factor, which is expressed in terms of basic invariants of the matrix deviatoric stress tensor and is used as an indicator for detection of differences in the loading mode. The material behaviour of UD composites with imperfect interface is assumed identical as for perfect interface and stiffness reduced fibres. Progressive failure criteria are established with consideration of fibre breakage and matrix crack for different fibre orientations. As a representative example for the NMFDM, a C30/E201 UD composite is studied. To verify the model, experiments are conducted on polymers, carbon fibres and UD CFRPs. Finally, the model is applied to simulate a perforated CFRP laminate, which shows excellent prediction ability on deformation, debonding and progressive failure.","lang":"eng"}],"status":"public","_id":"23431","department":[{"_id":"9"},{"_id":"154"},{"_id":"321"},{"_id":"149"}],"user_id":"15952","keyword":["Non-linear mean-field homogenization Average asymmetric plasticity of matrix Fibre–matrix interface debonding Micro-mechanical FE-simulation Progressive failure"],"article_number":"109209","language":[{"iso":"eng"}]}]
