    Abstract

    Crack arrest toughness KIa is considered to represent the minimum fracture toughness of a material. The crack arrest toughness standard ASTM E1221 defines a crack arrest toughness reference temperature, TKIa. TKIa is the temperature corresponding to a median crack arrest toughness value of 100 MPa√m. Previously, the TKIa temperature has been successfully correlated to the 4 kN crack arrest load transition temperature (TFa4kN) from the instrumented Charpy-V impact test for low to high strength steels. In this work, the correlation is expanded to cover also sub-sized specimens and ultra high strength steels.
