27 Aug '19

Hi everyone! The MSE and AAE graduate student organizations will be hosting a representative from the Business Office to present a training workshop for Ariba, the online purchasing system used by Purdue. If you are not yet familiar with Ariba, I strongly suggest attending this workshop, as you will need to use Ariba for nearly all lab-related purchases. First year students, even though you are not yet in a research group, this is extremely valuable to go ahead and learn. The workshop will be held on September 18, 2019 at 3:45 pm and should take no more than an hour. Snacks will be provided. In order to estimate how much we need in terms of refreshments, please RSVP using the link below by September 13th. https://docs.google.com/forms/d/e/1FAIpQLScwIJXY3mS0dJzzNcT_DmgGhrYs64nDVAe… [https://lh3.googleusercontent.com/w6qUBxKt48AoALdPgD9GPjhKkZIdBGiiTILleCuu6…]<https://docs.google.com/forms/d/e/1FAIpQLScwIJXY3mS0dJzzNcT_DmgGhrYs64nDVAe…> Ariba Training Session<https://docs.google.com/forms/d/e/1FAIpQLScwIJXY3mS0dJzzNcT_DmgGhrYs64nDVAe…> Event Time: June 18, 2019 3:45 pm Event Address: Armstrong Hall, Room B071 Direct any questions to Jessica Sargent at sargentj(a)purdue.edu<mailto:sargentj@purdue.edu> docs.google.com Thanks, and I hope to see lots of folks there!

Please consider attending the following: Please note the change of room EE 224 MATERIALS ENGINEERING SEMINAR "Application of Surface Severe Plastic Deformation to α+β and β Titanium Alloys for Microstructure Modification" By David A. Brice Purdue MSE Ph.D. Final Exam Advisor: Professor David F. Bahr ABSTRACT Gain refinement of metallic materials has become a popular topic for investigation because decreasing grain size improves mechanical properties; however, the production of large pieces/parts with refined grain structures is problematic. Early attempts to produce fine grained materials relied on gas condensation or milling processes that succeeded in producing nanocrystalline materials. These processes succeeded in producing small specimens that had nanocrystalline structures but exhibited decreased ductility. The use of severe plastic deformation processes, namely ECAP, have succeeded in producing ultra-fine-grained materials; however the uniform grain sizes still decrease overall ductility of the piece produced. Recently, surface deformation processes have produced localized refinement of the surface in metallic materials and reported an increase in strength along with ductility. This study focuses on the use of shot peening (SP) as a severe plastic deformation and its application to Ti based alloys, and has varied goals. Firstly, this project has used SP as a deformation process that coupled with a posthumous heat-treatment resulted in clear and consistent grain refinement in a variety of titanium alloys. The alloys used for this investigation were selected to represent classes of titanium alloys of interest to several industries, and more importantly to contrast the capabilities of lesser known alloys Ti-64. Application of SP produced clear grain refinement of surface layers that measured several microns from the surface. Significant hardening of the surface was measured as a result of the layers produced. Other effects from the processing such as precipitation of α-Ti in β-alloys was examined and shown to be influenced by elastic residual stresses. Also, the corrosion resistance of the layers was measured through Cyclic potentiodynamic polarization under conditions that mimic biological environment. Proof of concept for self-peening is reported in this study. Self-peening is the practice of performing SP with shot media composed of the same (or similar) material as the part that is being treated. Production of shot media was successfully performed through the exploitation of titanium oxidation. Evidence is provided that clearly shows decreased surface contamination when using the Ti-based shot media to shot peen Ti alloys. Additionally the surface hardening and residual stress imparted by the different shot media, while being used with identical shot peening conditions were compared.

Please consider attending the following: MATERIALS ENGINEERING SEMINAR "Direct Printing Conductive Layers onto Carbon Fiber Reinforced Polymers Substrate by Cold Spray Methodology" By Jung-Ting Tsai Purdue MSE Preliminary Exam Advisors: Professor Martin B. Jun and Professor David F. Bahr ABSTRACT Carbon fiber reinforced plastic (CFRP) have the advantage of lightweight and high specific strength. The low electrical conductivity of the CFRP can be fatal to lighting strike or electric current flow. Recent developments in cold spraying technology allowed to increase the electrical conductivity of CFRP. Unlike the conventional methods of attaching metal foils on CFRP, the direct printing in cold spraying (CS) method allows for a more flexible and maneuverable deposition of metallic patterns onto the surface of CFRP substrate. This research will discuss the cold spray process, the important factors determining cold spray efficiency and the advantages of cold spraying on CFRP. Literature sources reported the successful deposition of conductive particles on polymer materials. Currently, the explanation of the metal particle bonding to the CFRP is based upon the adiabatic shear instability (ASI) theory, which is widely accepted to explain the metal on metal bonding mechanism. The parameters of cold spraying process entail a specific microstructure that influences the mechanical properties of a sprayed CFRP. The implications of the control parameters of the CS process on the electrical conductivity and mechanical properties of a substrate CFRP should be further studied.

Note: this takes place on Wednesday, July 17: Please consider attending the following: MATERIALS ENGINEERING SEMINAR "Grain Growth Rate Transitions in Barium Strontium Titanate" By Matthew J. Michie Purdue MSE Ph.D. Final Exam Advisors: Professor Carol A. Handwerker and Professor John E. Blendell ABSTRACT Understanding grain growth of dielectric ceramics is essential to controlling the electrical and mechanical properties necessary to produce ceramic capacitors and sensors. The effect of alloying barium titanate with strontium titanate on the equilibrium crystal shape is being investigated in order to determine possible impacts on grain growth. The equilibrium crystal shape is being studied through three experimental methods to identify possible changes in the mobility or driving force with changing composition. The first method is by imaging intergranular pores to observe faceting behavior and relative interfacial energies. The second method is to perform atomic force microscopy on surface facets to collect topography data. The topography data is combined with orientation data obtained by EBSD analysis from the same region and is used to calculate the normal vector of the surface facets. The normal vectors are plotted in a stereographic projection to verify the faceting relationships observed in the pore shape analysis. The third method involves collecting EBSD orientation data and images of surface faceting behavior. The surface faceting behavior of each grain is categorized by type of facet and plotted on a stereographic projection at the corresponding orientation. This allows for the analysis of faceting transitions and the differentiation of faceted and continuous regions of the equilibrium crystal shape. The analysis of the equilibrium crystal shape of across compositions has implications on grain growth of the barium titanate/strontium titanate system. Date: Wednesday, July 17, 2019 Time: 9:00 A.M.
