    • 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.
