Measurement of Sintered Steel's Fracture Toughness by Repeated Impact with Low Energy

  • 摘要: 采用小能量多次冲击法测量了尺寸为12mm×12.5mm×62.5mm烧结碳钢的断裂韧性KIC值。考察了碳含量、冷却速度及后续退火工艺对粉末烧结钢的断裂韧性KIC值的影响。结果表明,烧结钢在小能多次冲击状态下的断裂韧性KIC值主要由烧结钢的强度决定。同时也需要一定的塑性与之相配合。
    Abstract: The repeated impact method with low energy,was adopted for measuring the fracture toughness of sintered carbon steels with sample size of 12mm×12.5mm×62.5mm.The effect of carbon content,cooling rate and anealing process on the sintered steels' fracture toughness was studied.The results shows that the fracture toughness,KIC value of sintered carbon steels,is dominated by their strength,and their ductility is necessary for improving the fracture toughness of thesintered steels.
