Acoustic emission during austenite decomposition into lower bainite with midrib

open access: yesArchives of Acoustics, 2014
Phenomena accompanying bainitic transformation in the range of swing back were investigated by using acoustic methods and microscopic analyses. It has been found out that midribs are probably formed in the first few dozen seconds.
