DGM-Interview: Mr. Karel Tesar - Winner of the MSE Poster Prize

J. Hirsch, K. Tesar, S. Klein, R. Münz

DGM-Press:Could you please introduce yourself and your research work?
Mr. Tesar: My name is Karel Tesar and I am a Ph.D. student partially at the Institute of Physics of the Czech Academy of Sciences which is located in Prague, Czech Republic and partially at my Alma mater which is Czech Technical University in Prague, Faculty of Nuclear Sciences and Physical Engineering. My main research topic consists of hexagonal metals (titanium, magnesium), their alloys and their properties. I am 25 years old and I have just started my first year of Ph.D. studies. For the first time I encountered materials science as a part-time job at the Institute of Physics which was offered to me by my current supervisor Dr. Ales Jäger when I was 19 years old. Dr. Jäger was looking for a student who could work on the metallography, sample preparation and characterization and I have found that to be a challenging opportunity. With this insight into an interesting field of metallurgy I have chosen the Department of Materials on my faculty to study this in more depth. I wish to thank the staff of Department of Materials for their time, since I have asked a lot of questions and they have always provided me much needed answers. Under the guidance of prof. Jiri Kunz and prof. Miroslav Karlík I have finished my Dipl. -Ing. title in the field of materials diagnostics with the supervision from Dr. Jäger with whom I closely collaborate on my current research.

Our research in the Group of Bulk Nanomaterials and Interfaces is focused on the advanced processing techniques and production of structural materials based on light-weight metals as well as the characterization of the resulting materials via SEM-EBSD, TEM and other methods. First of my research topics is nanocrystalline titanium produced by Equal Chanel Angular Pressing (ECAP) and its possible utilization for dental implants, with correlation to the texture-related mechanical anisotropy. The second topic which I pursue and which was partially on my poster at MSE 2016 is related to magnesium and its processing. We were able to prepare very thin Mg wires with diameter <250 µm and my Ph.D. thesis is related to their processing, deformation behavior and possible employment as a biodegradable material for medical applications. For microstructure characterization I use mostly SEM-EBSD technique which is an effective tool for in-depth analysis of the structure of metallic materials. Hopefully I will finish my Ph.D. in 2020 but I am not sure if our Group will stay at the Institute of Physics, since its scope is currently experiencing a transformation and the exact position of my research topics is yet to be known. However, I am positive that the topic of advanced structural light-weight metals and their use for implants and other applications will always find its way either on the Institute, my Faculty or on other institute of the Czech Academy of Sciences, since there is a number of very prestigious institutes on the national level and I wish to continue my work under a supervision of Dr. Jäger.

DGM-Press:How did you become aware of the MSE Congress? Did you like the Congress?
Mr. Tesar: My colleague M. Nemec from the Institute, also a Ph.D. student, recommended me this Congress and told me that he had already signed up for this event. He is using advanced TEM techniques to characterize severely deformed materials and together with Dr. V. Gärtnerová they are a crucial part of the Group regarding the TEM analysis which is also supporting my results. At first I was surprised that we should attend the same Congress since I didn’t recall MSE as a congress with such a large scope, but I was very pleased that I was able to attend lectures from various topics in which I am interested (structural materials, characterization, biomaterials, synthesis and processing…). I liked the Congress very much indeed and I think that it was well organized and the location in Darmstadt TU was very pleasant.

DGM-Press:Your poster was awarded the best prize at the MSE. What does this poster prize award means for you and in Czech Republic?
Mr. Tesar: I am very grateful for the award, since it has proven my research to be attractive, meaningful and provided me sometimes much needed motivation to pursue the effort to promote fundamental research in this field of structural materials. MSE is a well-known Congress so I would guess the award carries a positive impact in the Czech Republic.

DGM-Press:During the MSE did you have the opportunity to network with the international community?
Mr. Tesar: Yes. I spoke with various colleagues from different countries both during the poster session and after or between the lectures. I value their input on my work very much and I am grateful that they were all very kind and helpful.

DGM-Press:Did you have the opportunity to get to know the young professionals activities? (For example the US-German Networking Symposium, etc.)
Mr. Tesar: Indeed I had an opportunity to get to know young researchers, mostly during later stages of the poster session when there was time to chat with other people presenting their posters near me. Unfortunately I was not able to attend the Networking Symposium since I attended the Colloquium of Honor and other parallel lectures. On the other hand I did attend the MatWerk-Slam and although my German is rather bad I enjoyed it very much.

DGM-Press:Would you like to visit again the MSE-Congress 2018?
Mr. Tesar: I most certainly would like to visit MSE Congress in 2018 and if all goes well I will.

DGM-Press:Would you recommend the MSE-Congress to others?
Mr. Tesar: Definitely yes, it is a very interesting Congress and I like wide scope of this event. I also see as a big positive that many young researchers attend this Congress and therefore the networking is very intensive there.

DGM-Press: Mr. Tesar, thank you for this conversation. We wish you all the best for the future!
