            如何看待冷處理加工鋼材產品?

            模具鋼材是日常生活中隨處可見的一種產品。這些產品可以搭建房屋的結構,可以穩定它的組成成分。
            Die steel is a product that can be seen everywhere in daily life. These products can build the structure of the house and stabilize its components.
            其中常用的產品就是ASP60高速鋼,這種系列的鋼材產品具備的屬性無非就是它的硬度比其他產品的硬度還要更高一點,不易受到其他因素的影響。通常來說,ASP60高速鋼的硬度程度取決于它的碳元素含量,碳元素含量系數可以影響高速鋼的形成和性能。
            One of the most commonly used products is Asp60 high speed steel. The property of this series of steel products is that its hardness is higher than that of other products, and it is not easy to be affected by other factors. Generally speaking, the hardness of Asp60 high speed steel depends on its carbon content, and the carbon content coefficient can affect the formation and properties of high speed steel.
            熱處理加工是一種常見的加工手藝,經常應用在鋼材產品。不過冷處理加工也是運用在這些產品身上,它可以提升高速鋼的相關功能。對于冷處理加工鋼材產品,你是否知道和了解它的優點和不足呢?
            Heat treatment is a common processing technology, which is often used in steel products. However, cold treatment is also used in these products, which can improve the relevant functions of high speed steel. Do you know the advantages and disadvantages of cold-treated steel products?
            冷處理加工高速鋼的優點包含了這些方面。
            The advantages of cold treatment of high speed steel include these aspects.
            一、在強化金屬的同時可以獲得所需的形狀。
            1、 The desired shape can be obtained while strengthening the metal.
            二、可以獲得很好的尺寸公差和表面粗糙度。
            2、 Good dimensional tolerance and surface roughness can be obtained.
            三、價格便宜。
            3、 It's cheap.
            四、有些金屬只能進行有限程度的冷加工,因為它們在室溫下表現為脆性。
            4、 Some metals can only be cold worked to a limited extent because they are brittle at room temperature.
            五、冷加工削弱了延展性、導電性和耐腐蝕性。但因冷加工而導致的導電性減小的程度小于其他強化加工的影響,所以冷加工也被用來強化導電材料,如銅絲。
            5、 Cold working weakens ductility, conductivity and corrosion resistance. However, the reduction of conductivity caused by cold working is less than that of other strengthening processes, so cold working is also used to strengthen conductive materials, such as copper wire.
            六、如果各向異性的特性和殘余應力控制得當的話,它們也會帶來好處。如果控制不當,就會大大削弱材料性能。
            6、 If the properties of anisotropy and residual stress are properly controlled, they can also bring benefits. If not properly controlled, the material properties will be greatly weakened.
            七、由于冷加工的效果會在高溫下降低甚至消失,所以對于那些工作在高溫環境下的部件來說,不適用冷加工強化。不過呢,凡事都有兩面性,冷處理加工高速鋼產品的時候,也有不足的地方。例如冷加工會導致一些不需要的效果。比如延展性的降低以及殘余應力的增加。由于冷加工或加工硬化的機制是增加了位錯密度,因此任何可以重新排列或消除位錯的處理方法都可以消除冷加工的效果。
            7、 Because the effect of cold working will decrease or even disappear at high temperature, it is not suitable for cold working strengthening for those parts working at high temperature. However, there are two sides to everything. There are also deficiencies in cold treatment of high speed steel products. For example, cold working can lead to some unwanted effects. Such as the decrease of ductility and the increase of residual stress. Because the mechanism of cold work or work hardening is to increase the dislocation density, any method that can rearrange or eliminate the dislocation can eliminate the effect of cold work.
