영문 초록

Recen tly, th ere has been a change in steel from 2.25Cr 1Mo steel to P91(9Cr1Mo) steel for the purpose of high efficiency and po wer pl ant enlargeme nt. But, it was reported o ccasionally that cracks occur during operat ion in the welding heat affected zone on the structure made by P91 steel. Also, it has been reported that this is due to the formation of carbide pr ecipitates at the FGHAZ. So , in this study, the behavior of precipitate s during welding was analyze d and compa red with the results of crack sensitivity analysis by gleeble test.
