“…The nanoindentation testing of Young's modulus of austenite and ferrite in duplex stainless steel is reported not to be affected by sample surface treating methods, i.e., mechanical polishing, electrolytic polishing and chemical etching, whereas this is not valid for hardness; the nanoindentation testing of hardness of austenite and ferrite in duplex stainless steel is affected by surface treatment, here, mechanical polishing [46]. Therefore, the elastic modulus (E) is selected in order to generate the 3D map representation, denoting the difference in nanoindentation response due to phase properties underneath the The nanoindentation testing of Young's modulus of austenite and ferrite in duplex stainless steel is reported not to be affected by sample surface treating methods, i.e., mechanical polishing, electrolytic polishing and chemical etching, whereas this is not valid for hardness; the nanoindentation testing of hardness of austenite and ferrite in duplex stainless steel is affected by surface treatment, here, mechanical polishing [46]. Therefore, the elastic modulus (E) is selected in order to generate the 3D map representation, denoting the difference in nanoindentation response due to phase properties underneath the indenter, for (a) Blend 1 XY, (b) Blend 1 XZ, (c) Blend 2 XY plane, (d) Blend 2 XZ plane (Figure 12).…”
