Please consider attending the Preliminary Exam Seminar for Shikha Shrestha held Dec. 2, at 1:30 p.m., in ARMS 1021 "Effect of Rheological Behavior of Polymer Solution in Dry Spinning of Polymer Fibers" MATERIALS SCIENCE AND ENGINEERING SEMINAR "Effect of Rheological Behavior of Polymer Solution in Dry Spinning of Polymer Fibers" By Shikha Shrestha Purdue MSE Preliminary Exam Advisor: Professor Jeffrey P. Youngblood ABSTRACT Fiber spinning is one of the oldest polymer processing methods used for producing synthetic fibers. Depending on the specifications of polymer fibers, there are different types of spinning techniques - dry spinning, wet spinning and melt spinning. Dry spinning is one of the solution spinning methods in which the high vapor pressure polymer solution is introduced in the heating chamber, where it is converted to a solid fiber by controlled solvent evaporation in a spinline. There are many parameters that control fiber quality in dry spinning and includes rheological properties of polymer solution. They help to estimate the flow rate through the pipe and the capillaries of the spinneret and also when drawing fibers from the jet. The rheological properties of polymer solutions are affected by parameters like viscosity which increases with polymer concentration, molecular weight and decreases with temperature. Die swell is another variable influencing the rheological property and is bound to occur during the extrusion of filaments in dry spinning as a result of non-Newtonian shear flow of the spinning dope. Furthermore, for continuous and superior fibers, it is necessary to have a spinnable dope. The inferior fibers are formed due to the instability of the extrudate which is caused by capillary breakup and cohesive, brittle fracture. Hence, spinnability of polymer solution is required to form better fibers. Therefore, understanding the flow property of polymer-solvent mixture in dry spinning is necessary to obtain the ultimate continuous fibers with strong mechanical properties.

Please consider attending Eduard A. Caicedo-Casso's PhD Preliminary Exam Seminar held Dec. 3, in HAMP 2118, at 1:30 p.m. " Rheological Characterization of Triblock Polymer Solutions for Roll-to-Roll Membrane Production" MATERIALS SCIENCE AND ENGINEERING SEMINAR "Rheological Characterization of Triblock Polymer Solutions for Roll-to-Roll Membrane Production" By Eduard Andres Caicedo-Casso Purdue MSE Preliminary Exam Advisor: Professor Kendra A. Erk ABSTRACT New ultrafiltration membranes are created by self-assembly of block polymers and non-solvent induced phase separation techniques (SNIPS). Providing a platform with a hierarchical and well- defined porous network, these membranes offer high selectivity and permeability, along with good mechanical responses. It has been proven that SNIPS membranes could exhibit superior performance than the state-of-the-art commercial membranes. However, a major challenge towards the creation of a commercial product is to manufacture SNIPS membranes by continuous casting techniques. Hence, it is necessary to elucidate the fundamental physical principles of SNIPS casting solutions to start building a mass production casting process. It is believed that the SNIPS solutions' flow behavior has a strong correlation with the final morphology of membranes fabricated via roll-to-roll casting techniques. In this proposal, rheometry is introduced as a powerful tool to characterize the SNIPS solutions' flow behavior and to elucidate the structure- properties-performance interrelationships of SNIPS solutions.

Seminar for Xiaolong Bai, Thursday, Dec. 3, 8:30 a.m. ARMS B071, "Texture Evolution of Aluminum Alloy Sheets During Rolling and Annealing"

Please consider attending the Seminar for Xiaolong Bai, Thursday, Dec. 3, 8:30 a.m. in ARMS B071, for Preliminary Exam topic “ Texture Evolution of Aluminum Alloy Sheets During Rolling and Annealing” MATERIALS SCIENCE AND ENGINEERING SEMINAR “Texture Evolution of Aluminum Alloy Sheets During Rolling and Annealing” By Xiaolong Bai Purdue MSE Preliminary Exam Advisor: Professor Kevin P. Trumble ABSTRACT Crystallographic texture is one of the main factors responsible for the plastic anisotropy of aluminum alloy sheets. So it is important to understand the microstructure and texture evolution during rolling and subsequent annealing process. Conventional rolling process is plane strain rolling where only strains along ND (normal direction) and RD (rolling direction) exist. But when the shear between the rolls and the sheet surface is high enough, non-plane strain condition can develop. For plane strain rolling process, Cube texture {100}<001> dominates during reversible hot rolling process and in the subsequent multi-stand hot rolling and cold rolling process, all the initial textures rotate to the stable end 𝛽 fibre rolling texture. In the final annealing process, Cube {100}<001> and R {124}<211> texture prevail; for non-plane strain deformation process, however, shear texture {001}<110> and {111} // ND prevail, both in the rolling and subsequent annealing process. Conventional rolling process to produce aluminum sheets is energy intensive and the resulting textures, especially the Cube and Goss textures, are detrimental to surface quality and the formability of aluminum sheets. So a new shear-based single-step sheet processing technique-Large Strain Extrusion Machining (LSEM) is introduced in Prof. Trumble/Chandrasekar’s group.

Seminar for Suryanarayana V. Karra Tuesday. Dec. 1, 3:30 p.m. FRNY B124 "Phase Field Methods on Grain Growth Studies and Grain boundary Phase Transitions" PhD Preliminary Exam

Please consider attending the PhD Preliminary Exam Seminar for Suryanarayana V. Karra held on Tuesday, December 1, 2015, in FRNY B124 at 3:30 p.m. "Phase field Methods on Grain Growth Studies and Grain Boundary Phase Transitions" MATERIALS SCIENCE AND ENGINEERING SEMINAR "Phase Field Methods on Grain Growth Studies and Grain Boundary Phase Transitions" By Suryanarayana Vikrant Karra Purdue MSE Preliminary Exam Advisor: Professor R. Edwin Garcia ABSTRACT The shape, size and size distribution of grains affect the physical and mechanical properties of a wide range of materials for industrial applications. The experimental and computational studies of grain growth for shape and size distribution of grains are necessary steppingstones to first understand and then engineer the macroscopic properties. In this context, the aim of this report is to review the most representative contributions of the scientific literature on phase field models pertaining to grain growth in dense and porous polycrystalline structures. The types of models presented in this report include: (1) Landau Polynomial model, which is a multiorder parameter description based on a polynomial uniform free energy to study the grain coarsening of porous polycrystalline materials; (2) Multiphase field model, which is also a multiorder parameter model constructed on a pairwise interaction of order parameters to describe the grain growth of fully dense polycrystalline material; and (3) KWC (Kobayashi, Warren, Carter) model, which is an extension of a solidification model described by two order parameters: a crystallinity and local orientation order parameters. Landau Polynomial and Multiphase field methods fall short because of: (1) The extent of the model is constrained by number of grains of the system, (2) The grain boundary character is independent of the degree of misorientation. Similarly, the KWC model is only applicable to describe grain growth of fully dense polycrystalline materials. To study grain growth of porous polycrystalline materials, a model is proposed that brings together the best qualities of both the multiphase field and KWC models, including a degree of crystallinity, local orientation and concentration of vacancies. The structural stability of grain boundaries is described by extending a graphical construction proposed by Tang, and isomorphic to the one pioneered by Cahn, which shows that vacancies stabilize the grain boundaries from premelting.
