Research on Continuous Cooling Dynamic Transformation of T700

Article Preview

Abstract:

Continuous cooling dynamic transformation regularity of T700 was investigated by gleeble-3500. The results show when the cooling rate is small organization is mainly composed of polygonal ferrite and pearlite and has minor banded organization. With the increase of cooling rate, begin to appear granular bainite. When cooling rate reaches 3/s or more, ferrite changes to quasi polygon, and start to appear small amount of bainite. when the cooling rate is 7°C/s, pearlite is disappeared in structure, granular bainite increases, quasipolygonal ferrite content is gradually decreased. When the cooling rate is increased to 10°C/s or above, organization is granular bainite.
