Abstract Influence of a 12 T high magnetic field on the recovery of tempered martensite in the chromium-containing steel was investigated. The results showed that a high magnetic field caused the percentage of low angle boundaries θ between 5° ~ 8° to increase by about 8%, while correspondingly decreased the percentage of high angle boundaries (>15°) by 9%. With the application of the magnetic field, the strain energy increased due to the higher density of free dislocations in the martensite, which leads to the retardation of recovery and little change in its lath shape due to the inhibition of the transition from low to high angle boundaries to maintain lower energy in the matrix.

强磁场对回火马氏体恢复的影响

摘要 研究了12 T强磁场对含铬钢中回火马氏体恢复的影响。结果表明，强磁场导致5°~8°之间的低角度边界θ的百分比增加了约8%，而高角度边界（>15°）的百分比相应地减少了9%。随着磁场的施加，马氏体中自由位错密度增加，应变能增加，导致回复延迟，板条形状几乎没有变化，因为从低角度到高角度的转变受到抑制。边界以保持矩阵中的较低能量。
