• Crack Propergation of Lamellar Tearing on Modified Cranfield Type Cracking Test

抄録

To make clear the effect of inclusion-shape and distribution on the lamellar taering macro-pattern of fracture surface and direction of crack-propagation have been investigated. As the results, several modified cranfield type cracking test methods have been pi oposed. These cranfield tests have several built-up direction of weld beads against the rolling direction of steels. For comparison, some slow bend tests with same materials are used for the study.<BR>Following results were obtained.<BR>(1) In the cranfield test, the steels with many elonged inclusions have characteristic striped pattern in their fracture surfaces. Typical terrace-and-wall is obsreved in the cross section along the stripes.<BR>(2) Crack-behavior in the cranfield tests shows several different types, it depends on the built-up direction and inclusion-length or width.<BR>(3) Slow bend tests have same tendency of crack-behavior in cranfield tests.
