Physical metallurgy-guided machine learning and artificial intelligent design of ultrahigh-strength stainless steel (2019, methodology): “For example, physical models have been built to describe various strengthening mechanisms, such as classical precipitation strengthening by Orowan dislocation looping [16] and Friedel's shear cutting [17], solidsolution strengthening by Fleischer's model [18], dislocation strengthening by the Kocks-”
Predicting microstructure and strength of maraging steels: Elemental optimisation (2016, background): “ing is expressed in terms of a Hall–Petch equation for dblock [17,76], whereas the Taylor equation accounts for the strengthening contribution of the increase in the dislocation density.”
The role of the austenite grain size in the martensitic transformation in low carbon steels (2019, methodology): “As previously found by transmission electron microscopy in low carbon steels, the lath width remains essentially constant and independent of the PAGS, whereas the length of martensite laths scales with the PAGS [32,33,40].”
Multiple mechanisms of lath martensite plasticity (2016, background): “Since martensite blocks are separated by high angle grain boundaries restricting slip transmission, the effective grain size in martensitic microstructures is usually defined as the block size [24].”
