Formation of Structure and Properties of Low-Carbon Bainite in Steel

It can be seen from the thermokinetic diagram of decomposition of supercooled austenite (Fig. 2) that bainite forms in the steel in a wide range of cooling rates (up to 15 K/sec) and has peculiar structural features. To provide a relatively homogeneous and identical structural state, all the samples were subjected to 30-min normalizing at 940°C with cooling in still air at …

Phase formation during solidification of AISI 304

For the present casting conditions, the rate of solidification was very rapid and a maximum heat flux of 20 MW m −2 after 10 ms of the melt contacting the copper substrate was associated with nucleation in the melt [4]. Solidified samples of thickness of ∼1 mm were produced within 190 ms which indicates surface cooling rates greater than 10 5 K s −1.
