United way, pledge cards and bake sale
by Coar, Stacey L 29 Oct '15

29 Oct '15

Good afternoon all, As the United Way chair for MSE I wanted to end out an update on the United Way progress. Engineering is doing ok, we still have a lot of outstanding pledge cards, MSE has 38 no responses. If you have not given your pledge card to me or sent it in, please do so. Whether you pledge or not, please send your card in so at least we will have the responses calculated. If you prefer to make your pledge online or if you have lost your card, you can go to: 1) Online donation - you can make an online donation via this link: http://www.uwlafayette.org/givenow-purdue.html 2) Blank pledge form - you can download/print a blank pledge form and complete/return it to Dauch Alumni Center, United Way, Attn: Jamie Hendershot. Here is the link: http://www.purdue.edu/unitedway/pledgeforms.html One last thing.... Tomorrow there will be a bake sale in the Armstrong Atrium from 10-2 or until we sell everything, and there is going to be plenty :-) Thanks so much for giving to United Way!

In three dimensional reciprocal space maps of tensile deformed copper, individual, almost dislocation-free subgrains are identified from high-intensity peaks and distinguished by their unique combination of orientation and elastic strain; dislocation walls manifest themselves as smooth cloud of lower intensity. The elastic strain varies only slightly within each subgrain, but significantly between different subgrains. In average, subgrains experience backward strains, whereas dislocations walls are strained in forward direction. Based on these observations, the classical composite model is revised in accordance with the experimental findings. Furthermore, subgrain dynamics can be followed in-situ during varying loading conditions by high resolution reciprocal space mapping: During uninterrupted tensile deformation, formation of subgrains is observed concurrently with broadening of Bragg reflections shortly after onset of plastic deformation. The emergence of dislocation-free regions proofs irrefutably that ordered dislocation structures develop during tensile deformation. When changing the tensile direction after pre- deformation in tension, two distinct stages in the mechanical transient can be identified. During the initial stage, the number of resolved subgrains changes only slightly while their elastic stresses are altered significantly. In case of perpendicular tensile axes, reversal of the radial profile asymmetry is observed and rationalized.

In order to accommodate the increases in engine operating temperatures required for improved performance and efficiency, innovative alloying concepts and processing approaches have been developed to enhance the mechanical properties of Ni-base superalloys. These technological advances can largely be attributed to the development of physics-based computational models and novel characterization tools that provide an improved fundamental understanding of the intrinsic mechanisms governing their characteristic behavior. This talk will discuss some of the advances and challenges associated with developing engineering solutions to overcome these intrinsic limitations and extend the temperature capability of polycrystalline Ni-base superalloys. Dr. Sammy Tin is a Professor of Materials Engineering in the Department of Aerospace, Materials and Mechanical Engineering at the Illinois Institute of Technology. Professor Tin's research has focused on the composition - processing - microstructure - mechanical properties - performance relationships in polycrystalline and single crystal Ni-base superalloys. Prof. Tin is an internationally recognized expert in the field of superalloy creep, fatigue, oxidation and solidification. Professor Tin serves on the Editorial Committee for Materials Science and Engineering A and Metallurgical and Materials Transactions A. He was the recipient of the 2004 Rolls-Royce Mark Shipton Patent Award, the 2006 IOM3 Cook/Ablett Award and the 2007 ASM Marcus A Grossmann Award. He has also served as the Chair of the TMS High Temperature Alloys Committee and is currently on the Programming Committee of the 2016 International Conference on Superalloys. Prof. Tin has five patent applications and authored over 90 manuscripts in referred journals and conference proceedings.][cid:image021.jpg@01D10FCB.BEAE0B70] [Materials Engineering Fall 2015 Seminar Series]

Fwd: HVAC Work 10/23
by Donna Bystrom 22 Oct '15

22 Oct '15

FYI, Friday morning (10/23) our Physical Facilities staff will be carrying out some preventative maintenance work on one of our HVAC units. This particular unit provides air to the central portion of ARMS (elevators to atrium). Please keep in mind that you may notice little to no air flow during the first part of the day. Things should be up and running by lunch, if not earlier. Thanks, Phil Qualio <https://engineering.purdue.edu/Engr/People/ptProfile?resource_id=59120> Building Deputy Neil Armstrong Hall of Engineering Potter Engineering Center 765.496.9757 — 765.494.7020
