内容記述 |
Reheat cracking is used to occur in HAZs of Cr-Mo steels during reheating at the time the grain boundary is weekend by the phosphorus segregation. In this research, the effects of applied stress, and reheating time and temperature on the grain boundary weakening were clarified on HAZ of 1Cr-1/2Mo steel. A reheat cracking test and, metallurgical examination including grain boundary etching were carried out. Much attention was paid on the relation between the angle of each grain boundary line to the stress, and its phosphorus concentration. The following results were ontained. (1)In the temperature-raising process with a heating rate of 200K/hr, phosphorus concentration of grain boundary becomes maximum at 823K. (2)In the temperature-holding process in the range of 773 to 873K, the maximum value of phosphorus concentration is observed at 823K for 5 hours. (3)The phosphorus concentration is decreased by continuous heating up to 873K or by holding at 823K for a prolonged time. At this time period, the HAZ recovers from the weakened state. (4)The stress will intensity the phosphorus segregation in grain boundary by its direct action or by its indirect action of producing sliding at grain boundary. This mechanism was discussed in detail. |
