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.

钢组件仍然是现代汽车技术的核心，在那里，通过增加机械性能和耐腐蚀性来减轻重量。作为解决方案，淬火和分隔钢（Q＆P）以可行的成本提出了有希望的强度/延展性关系。但是，它们是许多与处理 - 微观建筑关系关系有关的未解决问题。基于上述情况，本批准后提案的三个主要目标参加了汽车材料的三个更紧急和必要的挑战。这些目标包括：1）详细说明和研究超级Q＆P钢，以改善当前微米材料所报告的限制的机械和腐蚀行为，2）通过一种新的质感组件与Q＆P钢性能之间的关系，通过新颖的实验方法， 3）通过制造纳米Q＆P钢来减少局部变形梯度。超铁和纳米结构钢的详细说明将最大程度地提高其最高容量的机械性能。该项目的结果将发挥关键作用，以设计和预测Q＆P钢的机械和物理行为。此外，预计QP1180钢的当前效率和汽车零件重量的减小。先前的结果将节省成本的产量，减少最终用户的燃油费用，并使二氧化碳生成更可持续的汽车使用。该项目不仅将在汽车材料方面提供新知识，而且还将使生产商的经济，最终用户，减少环境污染的产生以及提高欧洲汽车生产质量的经济。已计划将多学科特征技术的整合以及针对急诊室进行适当的项目管理和培训。
