摘要：

This study focuses on the characteristics of the toughness of a base plate and weld heat affected zone (HAZ), because its importance is becoming bigger in terms of a structural integrity. Several factors, such as reheating temperature, reduction per pass in the recrystallization region, and finish cooling temperature were varied to understand their effects on the base plate toughness. In order to examine how alloy elements can affect the toughness of the weld HAZ, a simulated HAZ technique was utilized and their effects were investigated by carrying out CTOD and Charpy impact tests. In addition, thick steel plates of 76.2 mm in thickness were produced and the toughness of the base plate and weld HAZ was evaluated to make sure if the factors which were proven to be effective on small scale specimens have an identical influence on the thick steel plates.
