摘要：

The creep behavior of a quenched and tempered Fe-Mo-C steel was investigated over the range of the magnetic Curie transformation from 875° to 1075°K. The apparent activation energy for creep was insensitive to the applied stress and had the same value over the primary and secondary stages. It exhibited the same type of hump at the Curie transformation temperature as that observed for the apparent activation energy for creep of α-Fe, which it exceeded by about 11,000 cal/mole. The secondary creep rate of this alloy increased with the 6.8 power of the applied stress in complete agreement with similar trends for α-Fe. The secondary creep rate, however, was about 10-3 that of α-Fe due principally to its higher activation energy for creep. © 1969.
