贝氏体非调质钢在高强韧结构部件领域具有广阔的应用前景。其在传统Mn-Cr系贝氏体非调质钢的基础上,通过添加少量Ni元素,研制了一种新型贝氏体非调质钢。钢中多元素协同调控赋予了材料潜在的性能优势,但需要制定合理的锻压工艺来激活这些潜力。通过在Gleeble-3500热模拟试验机上完成了不同温度(950~1 150 ℃)和不同应变速率(0.01~10

Bainitic non-quenched and tempered steel has broad application prospects in the field of high-strength and tough structural components. On the basis of traditional Mn-Cr series bainitic non-quenched and tempered steel, a new type of bainitic non-quenched and tempered steel has been developed by adding small amounts of Ni and V elements. The synergistic control of multiple elements in steel gives the potential performance advantages of the material, but it is necessary to develop a reasonable forging process to activate these potentials. The high-temperature compression tests under different temperatures (950 ℃-1 150 ℃) and different strain rates (0.01 s⁻¹-10 s⁻¹) were carried out on the Gleeble-3500 thermal simulation testing machine to study the hot deformation behavior of this bainitic non-quenched and tempered steel. Furthermore, an Arrehenius constitutive equation containing the Z parameter was established, which can well predict its high-temperature flow behavior. In addition, based on the dynamic material model and microstructure verification, a hot working diagram under a true strain of 0.7 was established. The obtained optimal hot working process range was as follows, the deformation temperature range was 1 050 ℃-1 150 ℃, and the strain rate range was 0.01 s⁻¹-0.22 s⁻¹. The strain rate of hot forging should be lower than 0.22 s⁻¹ to avoid the flow instability phenomenon during the deformation process.
