For the Institute of Metal Forming, the most productive of times

Graduate students, faculty and staff at the Institute for Metal Forming have taken part in half a dozen major international conferences in the U.S. and abroad in recent months.

Wojciech Misiolek, IMF director and Loewy Chair of materials processing, gave a paper on “Modeling and Characterization of Aluminum Extrusions: Modeling of Metal Flow and Microstructure Response” at the 5th International ESAFORM Conference on Material Forming in Krakow, Poland. This paper was co-authored by Van Geertruyden, Claves and Bandar. Misiolek also chaired a session at the conference.

Misiolek also gave a paper titled “Consolidation of Metal Powders during the Extrusion Process” at the 9th International Conference on Metal Forming in Birmingham, England. The paper resulted from Misiolek’s collaboration with the University of Mining and Metallurgy (UMM) in Krakow, and was co-authored with Kazanowski, M. Galanty of UMM and Panya Kansuwan, a graduate with IMF.

In October, Misiolek was a keynote speaker at the Brazilian Aluminum Association Conference in Sao Paulo and gave papers on “Extrudability of Aluminum Alloys.”

Later that month, he gave a keynote paper titled Analysis of Material Response to Processing Conditions: A Case Study of Aluminum Extrusion at the JSME/ASME International Conference on Materials and Processing 2002 in Honolulu, Hawaii.

Kelly Wardlow ’01, a teaching assistant in the College of Education, presented a poster in Washington, D.C., at Materials Education: Opportunities Over a Lifetime, a conference run by the Federation of Materials Societies. Wardlow’s poster was titled “Making Connections: An Example of Materials Outreach to the K-12 Community.”

Wardlow and Wojciech Misiolek have cultivated contacts with many local schools through an IMF outreach program. Next fall, the materials science and engineering department will offer a new class, Materials 196: The Education Option, to promote the materials field to middle- and high-school students, and to increase awareness of Lehigh’s materials science and engineering department.

Kai Lorcharoensery, a Ph.D. candidate in MS&E, gave paper titled “Hot Stage Microscopy of Nickel Coating on Iron Powder” at the Powder Metallurgy Conference in Orlando, Fla. The paper was co-authored with Misiolek.

Frank Gift, a graduate student in MS&E, gave a presentation on “Wheel Loading When Grinding a Nickel-based Superalloy using Water-based Grinding Fluids” at the Society of Tribologists and Lubrication Engineer’s (STLE) Conference in Houston. The talk was based on research performed with Quaker Chemical Corp. and was prepared by Gift, Misiolek and Ed Force II, an engineering technician in the department of industrial and systems engineering.

Steven Claves, a Ph.D. candidate in MS&E, gave a paper in Cambridge, England, at the 8th International Conference on Aluminum Alloys (ICAA8). His paper, “Analysis of the Intermetallic Phase Transformation Occurring During Homogenization of 6xxx Aluminum Alloys,” was based on work he performed in the summer of 2001 at V.A.W. of America (now Hydro Aluminum) in St. Augustine, Fla., and was co-authored with Misiolek and Donna Elias of V.A.W.

Claves and Misiolek presented a second paper at the ICAA8 conference that was co-authored with William Van Geertruyden, a Ph.D. candidate in MS&E, and also with Marcelo Goncalves and Marcelo G. Martins of the Institute of Technological Research in Sao Paulo, Brazil. The paper, titled “Homogenization and Hot Workability of Alloy AA2014,” grew out of IMF’s collaboration with the Brazilian institute.

Van Geertruyden gave a paper at the 13th International Conference on Texture of Materials in Seoul, South Korea, titled Formation of Recrystallization Textures After Hot Working of AA2014 and AA6063. The paper was co-authored with Misiolek and Goncalves, and also with Gisele Szilagyi of the Institute of Technological Research in Sao Paulo and Matt Nowell from TexSem Laboratories.

Pawel Kazanowski, an IMF postdoctoral research associate, presented the results of his research into bi-material tube extrusion at the annual review meeting of the U.S. Department of Energy’s Industrial Materials for the Future Program in Albuquerque, N.M.

Alexander R. Bandar, a Ph.D. candidate in MS&E, gave a paper on “Physical Modeling of Direct Extrusion through Weld Plates to Increase Yield” at the 7th International Conference on Technology of Plasticity (ICTP) in Yokohama, Japan. Bandar also met with Motoo Asakawa, a professor at the University of Waseda in Tokyo and a former visiting professor with IMF, to discuss potential collaboration between IMF and the Asakawa Laboratory of Waseda’s mechanical engineering department.
