3. Materials and Their Properties | 材料及其性能
Engineering materials are grouped into metals, polymers, ceramics and composites. For each category, candidates must understand key mechanical properties such as hardness, toughness, ductility, elasticity and tensile strength. Testing methods – including tensile tests, hardness tests (Brinell, Vickers, Rockwell) and impact tests (Izod, Charpy) – are a core part of the syllabus. The interpretation of stress–strain graphs for ductile and brittle materials is essential, with particular attention given to the yield point, ultimate tensile strength, and Young’s modulus.
工程材料分为金属、聚合物、陶瓷和复合材料。对于每一类材料，考生必须理解其主要机械性能，如硬度、韧性、延展性、弹性和抗拉强度。测试方法——包括拉伸试验、硬度试验（布氏、维氏、洛氏）和冲击试验（艾氏、夏比）——是课程的核心内容。解读韧性和脆性材料的应力–应变图至关重要，尤其要关注屈服点、极限抗拉强度和杨氏模量。
Material selection is always linked to the product’s function, manufacturing method and cost. For example, mild steel is commonly used for structural applications due to its strength and weldability, while aluminium alloys are preferred for lightweight components in aerospace. Polymers like ABS and nylon offer good mouldability for consumer products. The syllabus also covers the effects of alloying, heat treatment (annealing, quenching, tempering) and work hardening on material properties.
材料的选择始终与产品的功能、制造方法和成本联系在一起。例如，低碳钢因其强度和可焊性常用于结构应用，而铝合金则因其轻质特性被优先用于航空航天部件。ABS 和尼龙等聚合物为消费品提供了良好的成型性。大纲还包括合金化、热处理（退火、淬火、回火）以及加工硬化对材料性能的影响。
4. Manufacturing Processes | 制造工艺
A broad range of manufacturing processes is examined, including casting (sand casting, die casting), forming (forging, rolling, extrusion), machining (turning, milling, drilling, grinding) and joining (welding, brazing, soldering, adhesive bonding). Students need to describe each process, outline its advantages and limitations, and identify suitable materials. Modern additive manufacturing (3D printing) techniques such as FDM, SLA and SLS are also included, reflecting the move towards Industry 4.0.
