Cr12MoV钢是目前国内广泛使用的冷作模具钢之一。该钢具有淬透性好、硬度高且耐磨、热处理畸变小等优点,常用于制造承受重载荷和形状复杂的大型冷作模具。但该钢的显著缺点是脆性大,模具经常出现早期失效。因此,如何提高其强韧性,防止模具过早断裂失效,是该钢用户经常遇到且需
Cr12MoV steel is currently widely used in cold work die steel. The steel has the advantages of good hardenability, high hardness and wear resistance, small heat treatment distortion, commonly used in the manufacture of heavy duty and complex shape of large cold work die. However, a significant disadvantage of this steel is its brittleness, which often leads to early failure of the mold. Therefore, how to improve its toughness, to prevent premature failure of the mold, the steel is often encountered and the user needs
