The first model is an inverse model capable of predicting the initial microstructure required to obtain a desired final microstructure for use in nuclear forensics applications.\u0026nbsp; This inverse model describes the microstructure evolution of a monotectoid Zr-18wt.%Nb alloy by specifying the crystallographic orientation of the bcc beta-phase ZrNb.\u0026nbsp; By modeling the evolution of the crystallographic orientation the model attempts to provide information on how the material was processed and a framework which allows for the optimization of the mechanical material properties.\u0026nbsp; The second model is a forward model which utilizes two-point correlation functions to describe the phase distribution of the dual phase Ti-6Al-4V alloy in order to predict the final microstructure obtained after a known initial microstructure undergoes a specified processing procedure.\u0026nbsp; This model uses statistical continuum theory to describe the deformation of the two-point correlation functions and reconstructs the deformed statistics by systematic deformation of the initial two-point correlation function.\u0026nbsp; The last model is an inverse model which predicts the initial microstructure required to obtain a desired final microstructure using the two-point correlation functions described in the second model.\u0026nbsp; This model attempts to provide a computational model capable of providing optimization of material microstructure and thus mechanical properties for industrial applications.\u0026nbsp; Ultimately, the goal of these models is to reduce the industrial requirement of trial-and-error experiments for the development of new processing procedures and provide an avenue for the development of these new procedures through computational simulations.\u003C\/p\u003E\r\n\r\n\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E\r\n","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":"","field_summary_sentence":[{"value":"Materials-Affected Manufacturing: Simulating the Microstructure Evolution of Metal Alloys Through Processing\u201d"}],"uid":"27707","created_gmt":"2020-07-07 20:24:12","changed_gmt":"2020-07-07 20:24:12","author":"Tatianna Richardson","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2020-07-17T14:00:00-04:00","event_time_end":"2020-07-17T16:00:00-04:00","event_time_end_last":"2020-07-17T16:00:00-04:00","gmt_time_start":"2020-07-17 18:00:00","gmt_time_end":"2020-07-17 20:00:00","gmt_time_end_last":"2020-07-17 20:00:00","rrule":null,"timezone":"America\/New_York"},"extras":[],"groups":[{"id":"221981","name":"Graduate Studies"}],"categories":[],"keywords":[{"id":"100811","name":"Phd Defense"}],"core_research_areas":[],"news_room_topics":[],"event_categories":[{"id":"1788","name":"Other\/Miscellaneous"}],"invited_audience":[{"id":"78771","name":"Public"},{"id":"174045","name":"Graduate students"}],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[],"email":[],"slides":[],"orientation":[],"userdata":""}}}
