Lower bainite forms between 250 and 400 °C and takes a more plate-like form than upper bainite.  There are not nearly as many low angle boundaries between laths in lower bainite.  In lower bainite, the habit plane in ferrite will also shift from <111> towards <110> as transformation temperature decreases.  In lower bainite, cementite nucleates on the interface between ferrite and austenite.
