摘要
The temperature of dynamic strain aging(DSA) regime in P91 steel is between 250 ℃ and 500 ℃.The activation energy(Q) for onset of DSA is 73 kJ/mol,while that for finale of DSA is 202 kJ/mol.There are two main Internal friction(IF) speaks,Snoek and SKK with activation energy are 67.9 kJ/mol and 121 kJ/mol respectively,were observed.IFshows that activation energy of 73 kJ/mol is equal to that of C atom body diSusion in α-Fe,and 202 kj/mol is equal to binding energy between C atoms and moving dislocations.These results confirm the mechanism of DSA which is explained by the diffusion of C atoms and pinning between C and moving dislocation.From these investigation,it could be concluded that DSA in P91 steel are resulted from C atom diffusion and pinning dislocation,instead of Cr or Mo atoms.
