Exploration of Solution Space to Study Thermo-Mechanical Behavior of AA5083 Al-Alloy During Hot Rolling Process

A method is proposed to explore the solution space of a metallurgical process with an aim to foster material innovation through simulation based design. The efficacy of the method is demonstrated in the context of hot rolling of the AA5083 alloy. The set-based design approach is employed to predict the process parameters of rolling operation for a given set of specified requirements. Critical process parameters such as strain rate, temperature, heat transfer coefficient and strip width are only considered in the design study. Ternary plots are constructed and utilized to explore the solution space obtained and thereby identifying feasible regions of process operation wherein the specified requirements are satisfied. Since plant data is not available for the study, Finite-element (FE) analysis is carried out as a means to validate the results obtained using aforesaid design method.
