On the Brittleness of Heat-Affected Zone (Report 9)

Brittle Range Related to the Directionality of the Steel Plate

Abstract

Distribution of the toughness in the neighbour of weld, depending on the hysteresis and the directionality of the steel plate, are examined. Usability of the "Synthetic Impact Test Specimens" are considered. Max. brittle ratio of the heat-affected zone of the full-annealed steel plate seems to be greater than that of as-rolled steel plate. Synthetic impact values are greater slightly than the calculated one derived from the common impact method.
