The central objective of this project is to control the intermetallic compound (B2 type and L12 type) formation in Al-alloyed high strength high ductility steels with tailored properties. In this project, a thorough understanding on the intermetallic precipitation mechanisms should be achieved. The microstructure evolution and the elemental partitioning during the intermetallics formation in the steels with multiphase matrix are aimed to be intensively investigated by means of Calphad method and the experimental validations. Based on the knowledge of the intermetallics formation mechanisms, an effective scenario of controlling and utilization of the intermetallics as second phases in multiphase steels should be provided.

本项目的中心目标是控制具有定制性能的铝合金化高强度高韧性钢中金属间化合物（B2型和L12型）的形成。在本研究计画中，我们需要对金属间化合物的析出机制有一个深入的了解。本文采用Calphad方法和实验验证相结合的方法，对多相基体钢中金属间化合物形成过程中的组织演变和元素分配进行了深入研究。基于对金属间化合物形成机理的认识，提出了控制和利用金属间化合物作为多相钢中第二相的有效方案。
