摘要: The effects of different deformational parameters on true stress-true strain curves, tensile strength, microstructure and morphology of BR1500HS were investigated through tensile tests, metallographic optical microscope (OM), scanning electron microscope (SEM). The results show that different deformation parameter ranges have different effects on true stress-true strain curves and tensile strength. Both the increasing deformational temperature and decreasing strain rate can decrease the flow stress. At the temperature ranging from 800 to 900℃, the flow stress of material is small and the material's plastic is better, which greatly benefits material forming. At the deformational temperature ranges from 300 to 400℃, 500 to 700℃ and above 800℃, the corresponding major microstructures are martensite, bainite and austenite respectively with the same strain rate. Meanwhile, at the deformational temperature ranges from 300 to 400℃ and 500 to 900℃, the corresponding fracture mechanisms are brittle fracture and dimple fracture, especially at the temperature ranges from 800 to 900℃, the dimple fracture morphology is better. © 2016, Central South University Press.
