本课程主要是让学生了解并熟悉不同种类的常用工程合金与其应用-确保学生对工程合金设计做最优化的材

料选择。同时提供给学生对工程材料结构以及相关力学性能的理解，本课程还介绍如何使用不同的热处理

工艺和加工方法对材料的结构及性能的影响。另外，学生会了解到高级表征方法包括透射电子显微镜和三

维原子探针在相关金属与合金的跨尺度结构分析中的应用。

This course familiarizes students with the various types of major engineering alloys and their applications

- enabling them to make better decisions for materials selection for engineering designs. While providing

an understanding of engineering structures and how they relate to the mechanical properties of

engineering alloys, the course also offers information on how various heat treatments and processing

techniques cause changes in the structure and property of alloys. In addition, students will find some

advanced characterization methods including transmission electron microscopy (TEM) and 3D atom

probe tomography (APT) relating to metals’ and alloys’ microstructures from macro- to atomic- scale.
