Crack Failure Analysis on Kitchen Knife of 5Cr15MoV Steel

Article Preview

Abstract:

The cracking failure phenomenon of kitchen knife made by 5Cr15MoV steel was analyzed by chemical composition detection, hardness measurement, metallographic examination and SEM analysis methods. The results showed that the crack was mainly due to the organizational stress caused by carbide segregation in steel. Overhigh hardness and substandard chemical composition were the secondary cause of cracking.
