Georgy Raab is Head of the Laboratory for Severe Plastic Deformation (SPD) Technologies and an inventor of such SPD processes as ECAP-Conform, ECAP with parallel channels, Multi-ECAP-Conform and others. The main area of the laboratory’s activity is the experimental study of the equal-channel angular pressing technique, aimed at fabrication of bulk ultrafine-grained billets from ductile (Cu, Ni, Al) and hard-to-deform (Ti alloys, tungsten, molybdenum) metals and alloys. 

Currently Georgy Raab is the leader of several research projects funded by RFBR and the Russian Science Foundation.

In the last 5 years, he has published 133 papers and 1 monograph. His h-index is 21 (WoS).
