锻件是金属被施加压力，通过塑性变形塑造要求的形状或合适的压缩力的物件。这种力量典型的通过使用铁锤或压力来实现。锻件过程建造了精致的颗粒结构，并改进了金属的物理属性。下面，锻件厂则来介绍锻件的是三种偏折的原因。
A forged piece is an object that is applied to the metal by pressure to shape the required shape or the appropriate compression force by plastic deformation. This force is typically achieved by using a hammer or pressure. The process of forging has built a fine particle structure and improved the physical properties of the metal. Below, the Forgings Factory is to introduce the three reasons for the forgings.
锻件三种偏折的原因：
Three reasons for the deflection of the Forgings:
1、晶内偏析：该情况取决于浇铸时的冷却速度,偏析元素扩散能力和固相线倾斜度等、可以通过退火将偏析消除;
1, intragranular segregation: the situation depends on the cooling rate of casting, the diffusion ability of segregation elements and the inclination of solid phase line, etc., and the segregation can be eliminated by annealing.
2、区域性偏析：在较大范围内化学成分不均匀的现象,退火无法将该情况消除,这种偏析与浇温、浇速等有关；
2. Regional segregation: the phenomenon of uneven chemical composition in a large range can not be eliminated by annealing. This segregation is related to pouring temperature and casting speed.
3、比重偏析：合金凝固时析出的初晶与余下的液体存在较大的比重差，最终导致材料出现分层、化学成分不均匀的情况。可采用降低浇温加大冷却速度，加入微量元素形成比重适当等。
3, gravity segregation: when the alloy solidified, the primary crystal and the remaining liquid have a large proportion difference, which leads to the stratification and uneven chemical composition of the material. The cooling rate can be increased by reducing the pouring temperature, and the proportion of trace elements can be added to form the proper proportion.
