Micro-QpSteel Improving lifetime, decrease automotive pollution quenched & partitioned 1180 steel-made components by microstructural & texture tailor

钢铁部件仍然是现代汽车技术的核心，人们竞相通过提高机械性能和耐腐蚀性来减轻重量。作为一种解决方案，淬火和隔断钢(Q&P)在可行的成本下呈现出良好的强度/塑性关系。然而，与其加工-组织-性能关系有关的问题还有很多。基于上述，目前博士后建议的三个主要目标应对汽车材料这三个更紧迫和必要的挑战。这些目标包括：1)阐述和研究超细Q&P钢，以改善其力学性能和腐蚀性能，使其超过现有微米材料的极限；2)通过一种新的实验方法，研究特定织构成分与Q&P钢性能之间的关系；以及3)通过制造纳米Q&P钢来降低局部变形梯度。超细和纳米结构钢的精加工将使其最大限度地发挥其最大能力的机械性能。该项目的结果将在设计和预测Q&P钢的机械和物理性能方面发挥关键作用。此外，QP1180钢的电流效率有望提高，汽车零部件的重量将减轻。之前的成果将节省生产成本，减少最终用户的燃料费用，并通过减少二氧化碳排放使汽车的使用更可持续。该项目不仅将提供汽车材料方面的新知识，而且将有利于汽车生产商和最终用户的经济，减少环境污染的产生，并提高欧洲汽车材料生产的质量。为了项目的成功，已经计划整合多学科的定性技术，以及为应急方案进行适当的项目管理和培训。

The steel components remain at the core of modern automobile technology, where there is a great race to reduce the weight by increasing mechanical properties and corrosion resistance. As a solution, the quenching and partitioning steels (Q&P) present a promising strength/ductility relationship at a feasible cost. However, they are plenty of unanswered questions related to their processing-microstructure-properties relationship. Based on the above, the three main objectives of the present postdoctoral proposal attend the three more urgent and necessary challenges of automobile materials. These objectives include: 1) to elaborate and study ultrafine Q&P steels to improve the mechanical and corrosion behaviours beyond the reported limits for the current micrometric materials, 2) to study the relationship between specific texture components and Q&P steel properties through a novel experimental approach, and 3) to decrease the local deformation gradients through the fabrication of nanometric Q&P steels. The elaboration of ultrafine and nanostructure steels will maximize the mechanical properties of its top capacities. The results from this project will play a key role to design and predict the mechanical and physical behaviours of Q&P steels. Besides, an increment in the current efficiency of the QP1180 steel and a reduction of the weight of automobile parts is expected. Previous results will save cost production, decrease fuel expenses of final users, and make the use of automobiles more sustainable by lower CO2 generation. This project will not only provide new knowledge in the matter of automobile materials but also will benefit the economy of producers, final users of cars, decrease the environmental pollution generation, and raise the quality of European production of automobile materials. Integration of multidisciplinary characterization techniques, as well as proper project management and training for the ER, have been planned for the success of the project.
