Prof. Ing. Pavel LEJČEK, DrSc.

H-Index: 29

Institute of Physics of the CAS, Czech Republic, EU

Position: Head of Group "Materials with Controlled Microstructure - MCM" at the Institute of Physics of the CAS, Czech Republic, EU

At the METAL´22 conference, Prof. Pavel Lejček will present the lecture at the Session E Non-Ferrous Metals and Alloys.

Professional Background:
Prof. Pavel Lejček has received his M.S. degree (1973) in Physical chemistry at the Institute of Chemical Technology Prague (CZE) and PhD. (1983) in Physical metallurgy from the Institute of Physical Metallurgy of the CAS, Brno (CZE). In 1996 he has received a DSc degree from the Czech Academy of Sciences (Brno, CZE) in the field of Technical Sciences. He became an Assoc. Prof. in the field of Materials Chemistry and a professor of Metallurgy in 2005 (both at Institute of Chemical Technology, Prague, Czech Republic).

His professional career started at the Institute of Solid State Physics, CSAS, Prague, (now Institute of Physics, Czech Academy of Sciences) in 1973, where he was a researcher (from 1982) and from 1987 he led the Laboratory of Crystal Growth, department of Metal Physics. In the period 2000 - 2016, he was a head of the Division of Condensed Matter Physics. From 2016 to the present he is a visiting Professor at Kumamoto University, Kumamoto, Japan.

Activity in the last five years:

• Grain boundary segregation:
  • Development of a method for complete prediction of the chemical composition of individual grain boundaries at various temperatures in binary alloys of chosen composition. This method was proven for alpha iron base alloys.
  • Prediction of the possibility of entropy-driven grain boundary segregation (in case the energy/enthalpy of segregation is positive).

• Severe plastic deformation: Proposal of a new method of producing tubes from a rod in a one-step way consisting of several SPD processes.
• Powder metallurgy: interpretation of processes running in iron during selective laser melting (SLM) and explaining hierarchical microstructure of this material as well as mutual relationships appearing in the SLMed iron.

Stays Abroad
Prof. Lejček was a visiting scientist at ESME, St. Etienne, France in 2001 and 2002; at Tohoku University, Sendai, Japan in 2000 and 2005; at Univ. Pennsylvania, Philadelphia, USA in 1997 and 1999; at NRI, Tsukuba, Japan in 1997. He was the Max-Planck-Society visiting scientist at MPI for Metals Research, Stuttgart, Germany in 1992 and from 1994 to 1999. He was also at Max-Planck Institute for Metals Research, Stuttgart, Germany (Alexander von Humboldt Fellowship) in 1989 and 1991).
