Ferritic steel that ASTM E1921 master curve failed to characterize its fracture toughness temperature dependence by Toshiyuki MESHII

“…One finding was that this material showed fracture toughness of 100 MPam1/2 at higher temperature than room temperature, which is a rare case reported for the materials that MC is successfully applicable. Remembering Kirk’s opinion that “ASTM E1921 MC exists because MC of the yield temperature dependence (Zerilli equation) exists,” it was noted that the Zerilli equation showed poor fitting performance of yield stress over room temperature for this material. …”
