"Metals and Their Heat Treatment" is a crucial professional compulsory course for equipment manufacturing majors such as Intelligent Welding Technology, Physical and Chemical Analysis & Quality Inspection, and Additive Manufacturing Technology. It holds significant importance for students' subsequent courses and practical job tasks.
In the era of intelligent manufacturing, despite the disruptive transformations in manufacturing methods, the core requirements for fundamental knowledge and basic skills of metallic materials in the manufacturing process remain unchanged. Knowledge of metallic materials and heat treatment serves as an "invisible main thread" running through design, inspection, process, and machining. Its absence can lead to decisions in various stages deviating from scientific logic, ultimately resulting in a vicious cycle of "design flaws → manufacturing runaway → quality accidents," severely restricting a company's ability to upgrade to high-end manufacturing. Therefore, this course is not only a cornerstone in the field of materials science and engineering but also an essential carrier of "meta-skills" for engineers in the intelligent manufacturing era.
This course primarily covers the changing patterns among the composition, structure, and properties of metallic materials, as well as methods to alter material properties. It includes modules such as the properties and testing of metallic materials, the structure and microstructure of metallic materials, iron-carbon alloys, heat treatment of steel, industrial steels, cast iron, and non-ferrous metals.
Through studying this course, students will acquire fundamental theoretical knowledge in metallurgy, initially master the skills of rational material selection and utilization when designing engineering components and mechanical parts, and gain knowledge and abilities in correctly applying heat treatment, appropriately arranging processing routes, and conducting material testing. This course plays a pivotal role in cultivating engineering practical abilities, innovative awareness, and subsequent professional learning, while also laying a solid foundation for analyzing and resolving practical engineering problems in future work.
《金属材料与热处理》是智能焊接技术、理化分析与质量检测、增材制造技术等装备制造类专业至关重要的专业必修课，对学生后续课程的学习及未来实际工作任务具有重大意义。
在智能制造时代，尽管制造方式发生了颠覆性变革，但制造过程中对金属材料基础知识和基本技能的核心要求依旧未变。金属材料与热处理知识宛如一条“无形主线”，贯穿于设计、检验、工艺及机械加工等各个环节。若缺乏相关知识，各阶段决策就可能偏离科学逻辑，最终陷入“设计缺陷→制造失控→质量事故”的恶性循环，严重制约企业向高端制造转型升级。因此，本课程不仅是材料科学与工程领域的基石课程，更是智能制造时代工程师“元技能”的重要载体。
本课程主要涵盖金属材料成分、结构与性能之间的变化规律，以及改变材料性能的方法等内容。具体包括金属材料的性能与测试、金属材料的结构与组织、铁碳合金、钢的热处理、工业用钢、铸铁、有色金属等模块。
通过学习本课程，学生将掌握冶金学基础理论知识，初步具备在设计工程构件和机械零件时合理选材与用材的技能，并掌握正确运用热处理、合理安排加工路线以及进行材料测试的知识和能力。本课程在培养工程实践能力、创新意识以及后续专业学习方面发挥着关键作用，同时也为学生在未来工作中分析和解决实际工程问题奠定了坚实基础。
