The texture evolution of recrystallized austenite and deformed austenite in the plane strain compression test was investigated using optical microscope and electron backscattered diffraction (EBSD) by thermo-mechanical simulator. The results show that the plane strain state can be obtained because the two free-ends of the sample limit the transverse metal flow in the deforming zone. For the process of transformation texture of recrystallized austenite， the austenite transforms to allotriomorphic ferrite， bainite and a little pearlite， because recrystallization of austenite occurs and there is not obvious lattice distortion before transformation， and the transformation texture is100<011>α. For the process of transformation texture of deformed austenite， the austenite transforms to ferrite and pearlite due to the deformation in non-recrystallized austenite region， and the transformation textures are332<113>αand 113<110>α. The textures of the two processes are the typical transformation textures of hot rolling under plane strain. Thus， the plane strain compression test by thermo-mechanical simulator can create excellent plane strain state which is appropriate to investigate the evolution of hot rolling texture.
