  • Fracture toughness - Charpy impact test - Rockwell hardness regression based model for 51CrV4 spring steel
    Senčič, Bojan ; Šolić, Sanja ; Leskovšek, Vojteh
    Charpy V-notch (CVN) impact test values are widely used in toughness specifications for spring steels, even though the fracturing energy is not directly related to the spring's design. Both standard ... and non-standard methods for determining KIc are expensive and time consuming. In this paper, based on the results of experimental studies on spring steel grade 51CrV4, we have tried to find an expression so as to determine the fracture toughness from a computation based on the test results of the CVN and the Rockwell C hardness. This would be a much more economical and faster way to evaluate the fracture toughness of spring steels.
