Continuous cooling static transformation regularity of T700 was investigated by gleeble-3500, the results show when the cooling rate is small organization is mainly composed of ferrite and pearlite. With the increase of cooling rate, begin to appear granular bainite. When the cooling rate is 10-20 °C /s, microstructure is acicular ferrite and bainite. Along with the cooling speed further increasing, martensite begins to appear in organize, and with the increase of cooling rate, martensite content gradually increase. |
