MSE Seminar: Timothy Smith, Orientation and Alloying Effects On Creep Strength in Ni-Based Superalloys
Improved modeling of polycrystalline Ni-based superalloys requires a deeper understanding of the effects chemistry and orientation have on different creep deformation modes. Single crystal compression creep tests conducted under varying temperature and stress regimes were performed on two commercially available disk alloys, ME3 and ME501. Utilizing scanning transmission electron microscopy characterization techniques, twinning and superlattice extrinsic stacking faults were determined to be the active deformation mechanisms for the  oriented crystals. Ultra-high-resolution structure and composition analysis using energy dispersive spectroscopy, combined with density functional theory calculations, revealed differences in compositional variation along the extrinsic faults inside the g¢ precipitates between the two alloys. For ME501, this compositional variation corresponds with a shear induced solid-state phase transformation from g¢ to h phase. This nanoscale h phase creates a low-energy structure that inhibits thickening of stacking faults into twins, leading to significant improvement in creep properties and represents a newly discovered strengthening mechanism for Ni-base superalloys.
Tim Smith graduated from Bellefontaine City High School and attended Wright State University, obtaining a bachelor’s degree in Mechanical Engineering. During this time, he had the opportunity to work as a civilian research assistant at Wright-Patterson Air Force Base in the materials directorate. While there, he helped conduct research aimed at improving solid lubricant coatings and thermal interfaces in turbine engines. Afterwards, he decided to pursue his passion for materials science by working towards a PhD under Dr. Michael Mills at The Ohio State University. His thesis concentration is on how crystal orientation and alloying affects creep deformation in Ni-based superalloys through transmission electron microscopy analysis. Other projects that he has contributed to include, dislocation core analysis in high entropy alloys and improvements in characterization techniques using scanning transmission electron microscopy. He is currently a NASA Pathways Intern at the Glenn Research Center working on characterizing additively manufactured superalloys for the SLS engine and plans on working there full-time after graduation. When not working, his hobbies include; weight lifting, playing competitive sports and travelling abroad.

Transatlantic Cluster Conference on Lightweighting Technologies & Materials
February 15, 2017
140 Pfahl Hall, Blackwell Inn and Conference Center
2110 Tuttle Park Pl, Columbus, OH 43210
The German American Chambers of Commerce will bring their Transatlantic Cluster Roadshow to Columbus, Ohio, focusing on advances in lightweight materials. German and American cluster organizations will discuss best practices and share insights on: technology & materials; research & innovation; and international collaboration opportunities. The half-day conference will include brief presentations and panel discussions by US and German lightweighting experts:
- David Williams, PhD, Dean of the College of Engineering at The Ohio State University
- Ned Hill, PhD, Professor of Public Affairs and City and Regional Planning, Faculty Associate, Ohio Manufacturing Institute, The Ohio State University
- Brian Rice, Head, Multi-Scale Composites & Polymers Division, University of Dayton Research Institute
- Paula Watt, PhD, Director of Outreach, College of Polymer Science and Polymer Engineering
- Alan Luo, PhD, Professor, Materials Science Engineering and Director, Light Metals and Manufacturing Research Laboratory, The Ohio State University
- Wolfgang Schwarz, Project Manager “TraCLight”, Leichtbau-BW
- Dr. Tjark von Reden, Active Director of the Leading-Edge Cluster, MAI Carbon
- Tino Wollmann, Research Associate at the Institute of Lightweight Engineering and Polymer Technology, Technical University Dresden
Attend the event and learn where the lightweighting industry is going in Germany and the US, and how cluster organizations can support your business. Register here.
Following the conference, attendees can participate in tour of the Center for Design and Manufacturing Excellence, the Center for Electron Microscopy and Analysis, Edison Welding Institute, and the Center for Automotive Research.
Advisor: Dr. Roberto Myers
A FREE annual conference at the Ohio Union in Columbus, Ohio for Python programmers in and around Ohio, the entire Midwest, maybe even the whole world! There will be many Talks and Tutorials! Please be sure to bring your notebook and laptops and prepare to learn!

Presented by the Construction Systems Management Industry Advisory Council
Women Inspire Construction presented by The Ohio State University Construction Systems Management Industry Advisory Council is an event to gather the construction industry to focus on retention and community. Come to be empowered and join a conversation that leaves you inspired. The construction industry fosters long lasting relationships that lead to professional success. Both men and women are welcome to JOIN THE CONVERSATION!
Meet the panelists:
Nissa Beasley currently works as a Project Manager at TriVersity Construction with 24 years of experience in the construction industry. Nissa specializes in major renovation projects, lab construction and multi-story buildings and schools. She is also TriVersity’s subject matter expert with Phoenix Scheduling Program software and helps train project engineers on the program. Before joining TriVersity, Nissa worked for other high profile construction companies in the region.
Nissa received her B.S. in construction management from the University of Cincinnati. She serves as secretary on the board of NAWIC (National Association of Women in Construction) as well as a participating in its membership committee. Nissa was named NAWIC’s Cincinnati Chapter New Leader in 2017. Through NAWIC, she also volunteers for community events for children including Block Kids and the YWCA’s Rosie’s Girls
Heather Cassady currently work as a Project Manager on the $32M Canopy by Hilton hotel project located in Columbus, Ohio. She has been in the construction industry and with Turner Construction for 16 years. Throughout her years at Turner, Heather’s career has evolved in various management roles, including superintendent, sustainability manager, recruiting leader, and estimating engineer. Heather’s projects in Central Ohio have been in the healthcare, hotel, civic, and educational sectors.
Heather received her B.S. in Construction Engineering from the University of Akron. She is a LEED AP and serves as a community leader by dedicating her time and talent to support the National Association for Women in Construction (NAWIC), Women for Economic Leadership and Development (WELD) and the OSU CSM Industry Advisory Council.
Audra Smith currently works as a Project Executive for Pepper Construction and has extensive experience in construction management on large scale projects throughout central and northeastern Ohio. She has worked in the healthcare, higher education, mixed-use, and corporate office markets and has been involved in $578M worth of construction during her 15 year career. Her expertise is in client relationships and developing the appropriate processes, communication, and expectations to allow her project teams to be successful and meet the needs of the clients and owners. Prior to joining Pepper, she worked for Whiting-Turner Contracting and was responsible for all project interface, shutdown, and management of impactful construction to clients.
Audra earned a B.S. in Industrial Engineering from Pennsylvania State University and holds LEED AP BD+C credentials. She resides in Galena, Ohio with her sons Max and Vin. They share a passion for sports and her sons’ involvement in the Olentangy Local School District athletic programs afford her the opportunity to mentor, coach, and support their programs through fundraising and classroom academic activities.
