Our objective is to understand how solidifying aluminum alloys\u0027 microstructures are determined by the solidification velocity and alloy concentrations. We utilize state-of-the-art simulation results of ternary eutectoid Al alloy solidification (for further detail on the simulation see [1]). The simulations provide a data-rich transient solidification period that--in most cases--arrives at a steady state. In this talk I will present our methods and results for modeling the linkages between the simulated solidification process and the alloy microstructures.\u0026nbsp; I will also cover the ongoing challenges we have faced, which motivate the need of non-linear dimensionality reduction techniques for modeling transience in materials.\u003Cbr \/\u003E \u003Cbr \/\u003E [1] \u0026nbsp;- \u0026nbsp;H\u00f6tzer, Johannes and Jainta, Marcus and Steinmetz, Philipp and Nestler, Britta and Dennstedt, Anne and Genau, Amber and Bauer, Martin and K\u00f6stler, Harald and R\u00fcde, Ulrich (2015) Large scale phase-field simulations of directional ternary eutectic solidification.Acta Materialia (93), pp. 194-204.

As an undergraduate, he attended Rose-Hulman Institute of Technology majoring in computer science and mathematics. His academic interests are human-in-the-loop machine learning, visual analytics, and large-scale data mining. While in FLAMEL he aspires to utilize visualization and data mining techniques to improve the quality of models and material simulations. For fun he paints portraits and runs.\u003C\/p\u003E","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":[{"value":"\u003Cp\u003E\u003Cem\u003EThis\u0026nbsp;bi-weekly chalk \u0026amp; talk series, brought to you by the\u0026nbsp;\u003C\/em\u003E\u003Ca href=\u0022http:\/\/flamel.gatech.edu\/\u0022\u003EFLAMEL Traineeship Program\u003C\/a\u003E\u003Cem\u003E, focuses on topics in the areas of data and materials.\u0026nbsp;\u003C\/em\u003E\u003C\/p\u003E","format":"limited_html"}],"field_summary_sentence":[{"value":"This bi-weekly chalk \u0026 talk series, brought to you by the FLAMEL Traineeship Program, focuses on topics in the areas of data and materials."}],"uid":"27838","created_gmt":"2016-01-06 11:21:30","changed_gmt":"2017-04-13 21:17:19","author":"Holly Rush","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2016-02-25T10:00:00-05:00","event_time_end":"2016-02-25T11:00:00-05:00","event_time_end_last":"2016-02-25T11:00:00-05:00","gmt_time_start":"2016-02-25 15:00:00","gmt_time_end":"2016-02-25 16:00:00","gmt_time_end_last":"2016-02-25 16:00:00","rrule":null,"timezone":"America\/New_York"},"extras":[],"hg_media":{"314141":{"id":"314141","type":"image","title":"FLAMEL Traineeship Program","body":null,"created":"1449244929","gmt_created":"2015-12-04 16:02:09","changed":"1475895022","gmt_changed":"2016-10-08 02:50:22","alt":"FLAMEL Traineeship Program","file":{"fid":"199904","name":"flamel_traineeship_program.png","image_path":"\/sites\/default\/files\/images\/flamel_traineeship_program_0.png","image_full_path":"http:\/\/hg.gatech.edu\/\/sites\/default\/files\/images\/flamel_traineeship_program_0.png","mime":"image\/png","size":663273,"path_740":"http:\/\/hg.gatech.edu\/sites\/default\/files\/styles\/740xx_scale\/public\/images\/flamel_traineeship_program_0.png?itok=-yAkLmLc"}}},"media_ids":["314141"],"groups":[{"id":"1304","name":"High Performance Computing (HPC)"}],"categories":[],"keywords":[{"id":"15092","name":"big data"},{"id":"4096","name":"brown bag"},{"id":"208","name":"computing"},{"id":"438","name":"data"},{"id":"76181","name":"FLAMEL"},{"id":"79311","name":"FLAMEL Traineeship Program"},{"id":"10506","name":"IGERT"},{"id":"1692","name":"materials"},{"id":"77301","name":"NSF IGERT"},{"id":"25461","name":"Richard Fujimoto"},{"id":"166896","name":"seminar"}],"core_research_areas":[],"news_room_topics":[],"event_categories":[{"id":"1789","name":"Conference\/Symposium"},{"id":"1788","name":"Other\/Miscellaneous"},{"id":"1795","name":"Seminar\/Lecture\/Colloquium"},{"id":"1791","name":"Student sponsored"},{"id":"26411","name":"Training\/Workshop"}],"invited_audience":[{"id":"78751","name":"Undergraduate students"},{"id":"78761","name":"Faculty\/Staff"},{"id":"78771","name":"Public"},{"id":"174045","name":"Graduate students"}],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[{"value":"\u003Cp\u003EHolly Rush\u003C\/p\u003E\u003Cp\u003E404-385-1043\u003C\/p\u003E","format":"limited_html"}],"email":[],"slides":[],"orientation":[],"userdata":""}}}
