Introduction
Catalin Pruncu was working at the Design, Manufacturing and Engineering Management and the Advanced Forming Research Centre at University of Strathclyde. His focus was to fundamentally understand the flow forming process for aerospace applications. To do so, Catalin used EBSD technique to correlate the microstructure/GNDs evolution with mechanical behaviour of material subjected to forming processes.
