Seminar Notice for Jaehun Cho's Preliminary Exam, Thursday, Sept. 28, at 1:30 p.m., in ARMS 1028. "Mechanical Behavior of Yttrin Stabilized Zirconia at Microscale"
by Son, Rosemary E 21 Sep '17

21 Sep '17

Please consider attending the following: MATERIALS ENGINEERING SEMINAR "Mechanical Behavior of Yttria Stabilized Zirconia at Microscale" By Jaehun Cho Purdue MSE Ph.D. Preliminary Exam Advisor: Professor Xinghang Zhang ABSTRACT Yttria stabilized zirconia (YSZ) has metastable tetragonal phase at room temperature, which can transform into monoclinic phase with ~ 4% volume expansion under an applied external stress. The phase transformation (martensitic transformation) occurs near a crack tip where the external stress is concentrated and hinders a crack propagation by generating a compressive strain field, thereby enhancing toughness and strength. Recently, it is known that miniaturization of a specimen increases toughness of YSZ by decreasing mismatch stress among grains during martensitic transformation. Furthermore, it turns out that superelasticity and shape memory effect can be tremendously enhanced by scaling down the specimen. In this study, the concept of martensitic transformation and the factors affecting its effectiveness will be explored. Also, the mechanical properties of YSZ at macroscale and microscale will be compared. Lastly, the enhanced superelasticity and shape memory effect will be reported.

20 Sep '17

Reminder to attend the following: MATERIALS ENGINEERING SEMINAR "Study on Irradiation Response of Ferritin/Martensitic Steels" By Zhongxia Shang Purdue MSE Ph.D. Preliminary Exam Advisor: Professor Xinghang Zhang ABSTRACT This review paper mainly discusses the influence of irradiation induced volumetric swelling and hardening on the microstructures and mechanical properties of ferritic/martensitic steels. At the beginning, recent development and typical microstructures of ferritic/martensitic steels (9-12 %Cr) were introduced. Then swelling behaviors and hardening effects of the steels were investigated by a comparison with their austenitic counterparts. Finally, several mechanisms were summarized to explain the excellent swelling resistance but serious irradiation embrittlement of current ferritic/martensitic steels. This report provides a background for understanding the design of ferritic/martensitic steels for the future Generation IV nuclear reactors. Key words: generation IV nuclear reactors, ferritic/martensitic steels, volumetric swelling, irradiation hardening Date: Thursday, September 21, 2017 Time: 9:30 A.M. Place: ARMS 1021

Seminar Notice for Xingyao Gao's Preliminary Exam Seminar, Sept. 27, at 11:30 a.m., in ARMS 1028, "Strain Turning and Property Enhancement for Functional Oxides"
by Son, Rosemary E 20 Sep '17

Please consider attending the following: MATERIALS ENGINEERING SEMINAR "Strain Turning and Property Enhancement for Functional Oxides" By Xingyao Gao Purdue MSE Ph.D. Preliminary Exam Advisor: Professor Haiyan Wang ABSTRACT Functional oxides are recognized as potential next-generation electronic materials due to their wide variety of properties, including high-temperature superconductivity, ferroelectricity, colossal magnetoresistance, multiferroism. Functional oxides can be widely used in energy storage, dielectrics, ferroelectrics, superconductors, magnetic, spintronic devices and catalysts. In last two decades, tremendous progress of the thin film growth techniques such as pulsed laser deposition (PLD), magnetron sputtering, spin coating and molecular beam epitaxy (MBE) has been made. With the development of these techniques, precise control of the film growth can be achieved. Strain tuning is one of the most promising methods that can help to enhance the properties of the thin films. According to the origin of the strain, there are three approaches on strain tuning: substrate induced strain, multilayer induced strain and vertically aligned nanocomposite (VAN) induced strain. In this seminar, a brief introduction of each strain tuning approach will be given. Examples will be illustrated on how these strain tuning approaches could enhance the ferroelectricity, multiferroism and magnetoresistance of functional oxides.

Seminar Notice for Paul Mather's Preliminary Exam Seminar, Sept. 26, at 11:30 a.m., in HAMP 2107. "Exergy Modeling for the Pyrometallurgical Production of Copper"
by Son, Rosemary E 19 Sep '17

19 Sep '17

Please consider attending the following: MATERIALS ENGINEERING SEMINAR "Energy Modeling for the Pyrometallurgical Production of Copper" By Paul Mather Purdue MSE Ph.D. Preliminary Exam Advisor: Professor Matthew J. M. Krane ABSTRACT 80% of the world's copper is extracted pyrometallurgically. The three high temperature steps important to this process are smelting, converting, and fire-refining. These steps use much energy and are thermodynamically complex. Their literature has focused on modelling the process thermodynamics, kinetics, and furnace operation, with a goal to optimization. Publications linking these latter models to gain system-wide understanding are lacking. There are also no models which analyze entropy generation. As such, the opportunity exists for exploring total system behavior, including the furnace product quantity and quality, and energy, exergy, and feed material requirements, by the creation and linking of transient exergy models of them.

Please consider attending the following: MATERIALS ENGINEERING SEMINAR "Buckling Mechanics Metrology of Cellulose Nanocrystal Thin Films" By Mitchell L. Rencheck Purdue MSE Ph.D. Preliminary Exam Advisor: Professor Chelsea S. Davis ABSTRACT A major current need for sustainability is in the area of polyolefin plastics (grocery bags, disposable water bottles, milk cartons, etc.) that continue to contaminate our oceans as consumption progresses. Within the cell walls of wood lies a structural component called cellulose which has the potential to be a solution due to the high mechanical properties of the material (σ = 7.5 GPa and E = 110-220 GPa). Cellulose on the nanoscale is referred to as crystalline nanocellulose (CNC) and can be processed into thin films to be used as a suitable, sustainable replacement. Before CNC films can be implemented, proper mechanical characterization must be conducted. A technique utilizing buckling instabilities is identified as a solution, but cannot scale up to thicker films and conventional techniques struggle to deal with difficult CNC film properties. Free standing buckling mechanics are examined to present a viable solution for CNC film mechanical characterization. A novel mechanical testing frame was built to measure the critical buckling load of thin films. A cellulose acetate based transparent film was tested to find a critical load of 0.033N which yields an elastic modulus of 19.31 GPa. An overestimation was observed from insufficient equipment calibration and must be corrected before geometrical changes can be attributed to the transparencies to determine frame accuracy and precision. Once calibrated, CNC films will be tested to determine elastic moduli and anisotropy by varying load direction, crystal orientation, and crystal aspect ratio.
