Abstract
The fracture of hot-rolled, age-hardened super duplex stainless steel, Zeron 100, was investigated below the brittle/ductile transition. Unstable fracture may be preceded by brittle stable crack growth, particularly in thin sections, which increases the apparent fracture toughness. The most sensitive technique to monitor crack initiation depends on the crack orientation and the tendency for de-lamination in the rolling plane. A simple model predicts the crack initiation toughness for yield strength above 800 MPa. [on SciFinder(R)]
