热处理是机器零件及工具制造过程中的重要工序之一,对发掘金属材料强度的潜力,改善零件的使用性能,提高产品质量,延长寿命,具有重要的意义。热处理强化金属的效果得到日益广泛的重视。热处理原理是对钢的各种组织转变规律性的认识,钢经加热到奥氏体组织后,在不同的冷却条件下冷却,可使钢获得不同的力学性能。热处理工艺是热处理原理的具体应用。热处理原理部分的重点是C曲线。
Heat treatment is one of the important processes in the manufacture of machine parts and tools. It is of great significance to explore the potential of metal materials, improve the serviceability of parts, improve the quality of products and prolong the service life. Heat treatment to enhance the effect of metal has been an increasingly widespread attention. The principle of heat treatment is the understanding of the regularity of the various transformations of steel. When the steel is heated to austenite and cooled under different cooling conditions, the steel can obtain different mechanical properties. Heat treatment process is the specific application of heat treatment principle. Heat treatment principle part of the focus is C curve.
