ANNOUNCEMENT
IMS Announces Winner of 2019 IMS Buehler Technical Paper Award
© ASM International 2020
The 2019 winner of the Buehler Technical Paper Merit Award for Excellence, sponsored by Buehler, is “Metallographic Studies of Dissimilar Al–Cu Laser-Welded Joints Using Various Etchants” by Pascal Schmalen, Karthik Mathivanan, and Peter Plapper. The article was published in the February 2019 issue of Metallography, Microstructure, and Analysis. The award includes a plaque and a cash prize of $1000, endowed by Buehler. It will be recognized at IMAT 2021, which will take place September 13–16, 2021, in St. Louis, Missouri. Dr. Pascal Schmalen is a native of Luxembourg and attended the Technical University of Munich. After several internships, including one at the research reactor Munich FRM2, he gained an interest in research and started his Ph.D. program at the University of Luxembourg. There, he studied the laser welding of dissimilar Al–Cu, which included the analysis and characterization of intermetallic compounds. He holds an IWE diploma. In his current role, Dr. Schmalen is working as an R&D Scientist in the automotive industry on the challenging topic of printed electronics. Mr. Karthik Mathivanan has been a Doctoral researcher at the University of Luxembourg since 2018. He graduated with a master’s degree in mechanical engineering, specializing in industrial production from Politecnico di Milano, Italy, in 2017. During his master’s thesis, he worked on femtosecond laser cutting of nickel-titanium shape memory alloys in collaboration with CNR (National Research Council), Lecco, Italy. As a part of the Erasmus + traineeship in 2017, he conducted his research on microstructural analysis of braze welded Al–Cu, which led to the writing of the awarded paper in Metallography, Microstructure, and Analysis. He is currently pursuing his Ph.D. on fusion welding of Al and Cu with laser beam, where he is researching the techniques to suppress the formation of detrimental intermetallic compounds. Using signal processing of the spectral emission during the laser welding process, he aims to predict the weld strength of the Cu–Al connection. He collaborates with industries on welding of dissimilar metal combinations like Cu–Al, Al–Mg, and Cu–steel for automotive applications.

Prof. Dr.-Ing. Peter Plapper studied mechanical engineering at TU Kaiserslautern and did his doctorate at the Laboratory of Tool Machines (WZL) of RWTH Aachen. For 16 years, he worked in the European and American automotive industries in different management positions of Manufacturing Engineering (ME) with increasing responsibility. He developed innovative production technologies, implemented tool machines, and coordinated the refurbishment of assembly lines in numerous plants. Since 2010, he has been a full professor for Engineering Science at the University of Luxembourg. His research projects investigate manufacturing-related topics in all phases of the product development process, including process technology development
