A tailored tempering process, whereby the cooling rate for the sheet is controlled to form regions with very high strength and regions of reduced strength but increased ductility. In order to obtain the optimal mechanical properties for CSC-15B22 steel sheets that undergo tailored tempering, experimental and simulation method are used to examine the tempering process. The heated die section is heated from 150℃ to 500℃ to determine the effect of tooling temperature on the properties of the sheets. Results show that the section that is heated to a temperature of 150℃ is too strong to absorb energy due to an impact. The section that is heated to 500℃ shows a significant difference between the strength of the sheet for the heated and cooled sections of the tooling. The strength at the heated section is insufficient for vehicle B-pillars. For sheets that are heated to 350℃, a slight hot stamping effect is seen in the heated section of tooling. The strength of the steel sheet is increased and elongation is sufficient. An impact test result shows that if the tooling is heated to a temperature of 350℃, the formed steel sheet absorbs the greatest amount of impact energy.

模具温度对经过定制回火的CSC-15B22钢板力学性能的影响

量身定制的回火工艺,可控制薄板的冷却速率,以形成强度很高的区域和强度降低但延展性增强的区域。为了获得经过定制回火的CSC-15B22钢板的最佳机械性能,使用实验和模拟方法来检查回火过程。将加热的模具部分从150℃加热到500℃,以确定模具温度对板材性能的影响。结果表明,加热到150℃的断面由于冲击而强度太大,无法吸收能量。加热到500℃的截面显示出模具的加热和冷却部分的板材强度之间存在显着差异。车辆B柱的加热部分强度不足。对于加热到350℃的板材,在模具的加热部分会看到轻微的烫印效果。钢板的强度增加并且伸长率足够。冲击试验结果表明,如果将模具加热到350℃,则成形钢板吸收的冲击能量最大。
