• Review of Nanoindentation Size Effect: Experiments and Atomistic Simulation (2017, methodology): “[121] attributed the observed hardening to the decreasing dislocation segment lengths as the indentation depth decreases, which has a similar nature to the source truncation and weakest link theory mechanisms.”
• Selective laser melting enabling the hierarchically heterogeneous microstructure and excellent mechanical properties in an interstitial solute strengthened high entropy alloy (2019, background): “Besides, the KAM values (Figure 3(b1–b4)) increased apparently with the strain, suggesting an increasing density of geometrically necessary dislocations [19].”
• Quantification of the effect of transformation-induced geometrically necessary dislocations on the flow-curve modelling of dual-phase steels (2013, background): “D structure of the lattice rotation fields (Zaafarani et al., 2006, 2008; Rester et al., 2007, 2008; McLaughlin and Clegg, 2008; Kiener et al., 2006; Demir et al., 2009; Man et al., 2010).”
• On Strain Hardening Mechanism in Gradient Nanostructures (2021, background): “Since non-uniform deformation is generally associated with GNDs (Ashby, 1970; Demir et al., 2009; Fleck and Hutchinson, 1993; Gao et al., 1999; Lyu et al., 2015; Martínez-Pa ~ neda and Niordson, 2016), it is important to incorporate the effect of GNDs in the present model.”
• The effect of crystal orientation on the indentation response of commercially pure titanium: experiments and simulations (2010, methodology): “The EBSD technique allows larger, more realistic and more deformed samples to be characterized compared to TEM-based studies (Demir et al. 2009; Rester et al. 2008; Zaafarani et al. 2008).”
• Hierarchical microstructure design to tune the mechanical behavior of an interstitial TRIP-TWIP high-entropy alloy (2019, methodology): “The fractions of the GNDs of 1014/m2 (KAM values above 1) were obtained from the KAM plots [44,45].”
