웹2024년 6월 4일 · V. Bainite. Bainite is the product of transformation of austenite below pearlite transformation zone and above MS point in medium temperature zone. Bainite is a mechanical mixture of ferrite and cementite, a structure between pearlite and martensite, expressed in symbol B. 웹Bainite is a plate-like microstructure that forms in steels from austenite when cooling rates are not rapid enough to produce martensite but are still fast enough so that carbon does not have enough time to diffuse to form pearlite.Like pearlite, the constituent phases of bainite are ferrite and cementite. Diffusional processes during cooling are involved in its formation. 웹Bainite. W.T. Reynolds Jr., in Encyclopedia of Materials: Science and Technology, 2001 2 Displacive Mechanism.

The relatively high dislocation density associated with bainitic ferrite can be attributed to a shape change accompanying the transformation which is accommodated at least …

웹2024년 9월 11일 · The substructure of granular bainite has been revealed by TEM; granular bainite is composed of parallel fine elongated platelets with a thickness of ∼0·5 μm. The parallel fine elongated ferrite platelets have a similar orientation and form a sheaf morphology, which is no different from that of ordinary bainite. 웹A bainite dual-phase (FB) steel containing polygonal ferrite and granular bainite is thermo-mechanically rolled, followed by an accelerated cooling. Two different cooling rates are applied to obtain two different materials.
