Research and Application of Grain Structure Control Method for High-level Pipeline Steel
摘要
Abstract
The several common used methods of controlling grain structure of high-level pipeline steel and the application of all kinds of technologies at present were discussed, the hot problem was analyzed. The application of improving the toughness of welding heat affected zone( HAZ) in high-level pipeline steel by adding second phase particle was explained, and the latest progress, existing problems and further development of controlling grain structure in the future was analyzed.关键词
