The effects of warm rolling reduction ratio ranging from 20% to 55% on microstructure evolution. the tensile deformation mechanism. and the associated mechanical properties of an Fe-30Mn-4Si-2Al TRIP/TWIP steel were studied. The warm rolling process resulted in the formation and proliferation of sub-structure. https://kdaicxlxj4ap3n.aioblogs.com/87843823/factor-analysis-of-ways-to-activate-using-the-urban-passenger-motor-transport
