Popis:	In this paper, multi-pass hot compression experiments of pure titanium TA1 was investigated with Gleeble-3500 thermal simulation test machine at an initial temperature of 880°C. The purpose is to investigate the effects of hot compression on the deformation of a electron beam cold hearth melting (EBCHM) single casting TA1 slab. The microstructure of the sample was analyized by metallograph and electron backscatter diffraction (EBSD), and the dynamic recovery was found to be the main recovery mechanism. The recrystallization nucleation mechanism were mainly bulging at grain boundary and merging of sub-grain.
