| 1. | With improvement of material composition and processing , the failure modes demonstrate predominately elevated wear and plastic deformation , and no earlier failure occurred , leading to a considerable improvement of service life and a stable number of 6000 ~ 7000 times , 80 % more than forging steel dies
经改进材质及工艺后，热磨损、塑性变形为主要失效形式，而未出现早期断裂失效，寿命得到明显提高，稳定在6000 ~ 7000件，高于锻造模具钢80 %以上。 |
