The Hall-Petch and the Orowan relationship could only be applied to some of the investigated microstructures, whereas the work-hardening formula which correlates flow stress with dislocation density was more generally valid, provided that dislocation density was measured in the deformed state. In ...

An increase of the austenite nuclei density that formed in the LM leads to the accelerated transformation of reversed austenite during non-isothermal continuous heating, as compared to the austenite formed with initial microstructure of granular bainite. In addition, reverse transformation of martensite ...
1(a–c). AF is a needle-shaped fine ferrite, and is grouped by packets having high-density interior dislocations and high-angle boundaries which are effectively resistant to the cleavage crack propagation on {100} planes, thereby showing a good strength-toughness combination26,27,28. GB ...

The electropolishing was performed at a voltage and current of 25 V and 55–65 mA, respectively, using a 7% perchloric acid/glacial acetic acid mixture under room temperature. The fraction of retained austenite (RA) and the density of dislocations in each sample were determined via quantitative ...
