若因温度和变形程度选择不当而得到粗大晶粒时，可利用热处理相变细化晶粒组织，但对于热处理中不发生相变的钢种，如奥氏体钢，就必须在锻造过程中获得细小而均匀的晶粒组织，因此对这样的材料在锻造时须加倍注意。

If the temperature and degree of deformation and improper selection of coarse grains, the grain refinement phase change heat treatment, but for the steel phase transition does not occur in the heat treatment, such as austenitic steel, it must be in the forging process have fine and uniform grains, so this kind of material in the forging must pay more attention to.

由于热变形形成纤维组织，会使金属的力学性能出现异向性，即纵向力学性能指标中的A，Z，Ak比横向相应的指标大得多，两个方向上的强度Rm。Re差别不大。

Due to the formation of fibrous microstructure by thermal deformation, the mechanical properties of metals will be different. That is, A, Z and Ak in longitudinal mechanical properties are much larger than those itransverse direction, and the strength in two directi is Rm. Re is not very different.

不知道听到工艺两个字的时候我们更多的想到的是什么?我想很多人对工艺的追求大多体现在对一些艺术品上面。其实不仅仅是艺术品对工艺的要求非常高。在我们的机械领域对工艺也是精益求精的，因为只有高超的工艺才能制造出更的产品，就比如说大口径法兰对它的工艺要求也是很高的。Specialforgingsincluderollforging,crosswedgerolling,radialforging,liquidforgingandsoon。

I don't know what we think about more when we hear the two  of the craft?在进行锻造作业时，几个操作者之间要集中精力，互相配合，躲开危险方向，选择相对安全的位置。 I think a lot of people's pursuit of the craft is mostly on some of the works of art. In fact, not only is the art of art demanding very high technology. In our field of machinery, we also strive for improvement in technology, because only superb technology can make more perfect products, for example, large diameter flanges require high technological requirements for them.
