    如何看待冷处理加工钢材产品?

    来源:https://www.jnqhmj.com/ 日期:2021-06-23 发布人:admin


    模具钢材是日常生活中随处可见的一种产品。这些产品可以搭建房屋的结构,可以稳定它的组成成分。
    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.
    其中常用的产品就是ASP60高速钢,这种系列的钢材产品具备的属性无非就是它的硬度比其他产品的硬度还要更高一点,不易受到其他因素的影响。通常来说,ASP60高速钢的硬度程度取决于它的碳元素含量,碳元素含量系数可以影响高速钢的形成和性能。
    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.
    热处理加工是一种常见的加工手艺,经常应用在钢材产品。不过冷处理加工也是运用在这些产品身上,它可以提升高速钢的相关功能。对于冷处理加工钢材产品,你是否知道和了解它的优点和不足呢?
    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?
    冷处理加工高速钢的优点包含了这些方面。
    The advantages of cold treatment of high speed steel include these aspects.
    一、在强化金属的同时可以获得所需的形状。
    1、 The desired shape can be obtained while strengthening the metal.
    二、可以获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、价格便宜。
    3、 It's cheap.
    四、有些金属只能进行有限程度的冷加工,因为它们在室温下表现为脆性。
    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、导电性和耐腐蚀性。但因冷加工而导致的导电性减小的程度小于其他强化加工的影响,所以冷加工也被用来强化导电材料,如铜丝。
    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、如果各向异性的特性和残余应力控制得当的话,它们也会带来好处。如果控制不当,就会大大削弱材料性能。
    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、由于冷加工的效果会在高温下降低甚至消失,所以对于那些工作在高温环境下的部件来说,不适用冷加工强化。不过呢,凡事都有两面性,冷处理加工高速钢产品的时候,也有不足的地方。例如冷加工会导致一些不需要的效果。比如延展性的降低以及残余应力的增加。由于冷加工或加工硬化的机制是增加了位错密度,因此任何可以重新排列或消除位错的处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.
