- 論文の詳細を見る
The influence of the amounts of M-A constituent in simulated HAZ on notch toughness was investigated for HSLA steels. Post-heat treatment tests at 823 and 923K were made to investigate the metallurgical behaviour and ductility change. consequently the relation between the amount of M-A constituent and recovery of notch toughness was investigated. Moreover secondary hardening and temper embrittlement appeared in steels HT100 were analyzed. Generally it can be said that, when the HAZ steels contains a large amount of M-A constituent, the improvement of notch toughness could be associated with decomposition of this phase.
