分析讨论了影响粉末锻钢冲击韧性的因素和近年来为改进粉末锻钢冲击韧性在国内外的进展。为进一步提高粉末锻钢的冲击韧性，进行了降低粉末锻钢的氧含量和热处理试验。发现长时间扩散退火可显著提高粉末锻件的冲击韧性。
The factors influencing the impact toughness of powder forged steel and the progress in improving the impact toughness of powder forged steel in recent years are analyzed and discussed. In order to further improve the impact toughness of the powder forging steel, the oxygen content and the heat treatment of the powder forging steel were reduced. It has been found that prolonged diffusion annealing can significantly improve the impact toughness of powder forgings.
