The course of "Engineering Materials" is based on materials science and engineering disciplines with mechanical manufacturing and transportation engineering disciplines as the application background. It is a course for undergraduates majoring in materials, machinery, and automobiles which is transdisciplinary and foundational. The online course has a total of eight chapters, and a duration of about 400 minutes. 

        The main teachers of the course are all backbone teachers who have long struggled in the field of teaching and research of materials majors, and have rich teaching experience. The course is based on physics, chemistry, material mechanics, mechanical manufacturing and other courses. It mainly introduces the basic knowledge of mechanical engineering materials including material properties, material structure, solidification and crystallization of materials, plastic deformation and recrystallization of metals, iron carbon, steel heat treatment, alloy steel, cast iron and other professional content.

        In the process of teaching, we should not only pay attention to systematic theoretical learning, but also combine professional needs, attach importance to experimental links, connect theory to production practice, and follow the practice-theory-practice rule to cultivate students' ability to analyze and solve problems. The course teaching firmly grasps the two major supporting points of scientific research and technology application, and ultimately serves the high-end machinery and equipment manufacturing industry and forms the characteristic development goal of this course.

Engineering Materials is a technical basic course based on the courses of physics, chemistry, material mechanics, mechanical manufacturing foundation, and so on. At the same time, it is also the basis for learning subsequent courses.

Therefore,during the learning, we must not only pay attention to systematic theoretical learning on the basis of relevant courses, but also combine professional requirements to connect theory with production practice, attach importance to experimental links, and follow the rule of practice-theory-re-practice to learn, in order to develop students' ability to analyze and solve problems.

The contents of this course mainly include mechanical engineering material properties, metal, heat treatment and common mechanical engineering materials. The learning objectives of this course are as follows:

1、Performance: mainly understand the main mechanical properties of materials: yield strength, tensile strength, elongation, reduction of area, impact toughness, hardness, fatigue strength, fracture toughness, wear resistance and other test principles and practical production significance;

2、Metallurgy: understand the basic theory of material structure, crystallization process, binary alloy phase diagram, plastic deformation and recrystallization, to lay the foundation for further study of heat treatment and material selection;

3、Heat treatment: understand the basic principles and processes of heat treatment of iron and steel materials, as well as the status and role of heat treatment processes in parts processing, so as to properly select heat treatment process methods and rationally arrange process routes;

4、Engineering materials: master the composition, organization, properties and use of commonly used carbon steel, cast iron, alloy steel, nonferrous metals and their alloys; understand the classification, properties and use of common non-metallic materials such as engineering plastics, rubber, ceramics, composite materials, in order to select engineering materials reasonably.
