Nano-characterization technique for steel research by using aberration corrected scanning transmission electron microscopy

Nano-characterization of steel by using aberration corrected scanning transmission electron microscopy (STEM) is outlined. The analysis of boron segregation on the prior austenite (γ phase) grain boundary in a boron added steel plate and TiC precipitates in a high strength hot rolled steel sheet were presented. Through these application examples it was found that the aberration corrected STEM was quite useful for nano-characterization in advanced steel.
