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，淬火和分区钢（Q&P）在可行的成本下呈现出良好的强度/塑性关系。然而，它们的加工-微观结构-性能关系仍有许多未解决的问题。基于以上，本博士后计划的三个主要目标是针对汽车材料的三个更为迫切和必要的挑战。这些目标包括：1)精心设计和研究超细Q&P钢，以改善目前微米材料的机械和腐蚀行为，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)通过纳米Q&P钢的制造减少局部变形梯度。超细和纳米结构钢的细化将最大限度地发挥其最大的机械性能。该项目的结果将在设计和预测Q&P钢的力学和物理行为方面发挥关键作用。此外，QP1180钢的电流效率也有望提高，汽车零部件的重量也有望减轻。先前的成果将节省生产成本，降低最终用户的燃料费用，并通过降低二氧化碳排放量使汽车的使用更具可持续性。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者和最终用户的经济，减少环境污染的产生，提高欧洲汽车材料生产的质量。为使项目取得成功，已计划综合多学科特征技术，以及适当的项目管理和急诊室培训。

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.
