为了得到碳化物分布均匀的高合金工具钢材料,对比了扁方圆和方圆2种锻造方法对共晶碳化物的分布特点及晶粒大小的影响,发现采用扁方圆的锻造方法可以更有效地破碎钢材芯部的碳化物,改善碳化物条带状分布。
In order to obtain high-alloy tool steel with uniform distribution of carbides, the effects of two kinds of forging methods on the distribution characteristics and grain size of eutectic carbide were compared. It was found that the forging method with flat square circle can be more effectively broken Carbide in steel core improves carbide strip distribution.
