Characterization of the elasto-plastic properties of 0Cr12Mn5Ni4Mo3Al steel by microindentation

Investigation on Behavior of Elastoplastic Deformation for Ti–48Al–2Cr–2Nb Alloy by Micro‐Indentation and FEM‐Reverse Algorithm

“…In Figure c and d, the damage of indentation experiment was shown. It can obviously see that the damage is directly proportional to the maximum load (or indentation depth), while the relationship between 1/ and 1/ h is almost linear, as reported in ref . And the damage phenomenon is the subject in our further study.…”

A strain-dependent ductile damage model and its application in the derivation of fracture toughness by micro-indentation

“…Micro-indentation experiments were performed on α phases using the commercial MCT W501 equipped with a Berkovich diamond indenter at room temperature under the laboratory environment. Some researchers [34,35] …”

“…Based on the calculation formulas for Young's modulus E from references [34][35][36], the relationship between apparent Young's modulus and indentation depth can be obtained easily, namely E-h p and its natural logarithm curves in Fig. 9.…”

Investigation on mechanical property of annealed copper particles and cold sprayed copper coating by a micro-indentation testing

“…Five indentations were made at each test force to obtain the average result. The parameters of holding time and loading speed in the test were 0 s and 9.6841 mN/s, respectively [13,22]. The calculation model of Oliver and Pharr [23] was applied to process different force-displacement curves, acquiring the changing laws of corresponding hardness and Young's moduli versus test forces.…”

“…Numerous dislocations existed in some areas of Cu coating, and also ultrafine grains approximately 100 nm-1 lm and some deformation twins existed [12]. Recently, Xue et al [13] investigated the micro-mechanical behavior of 0Cr12Mn5Ni4-Mo3Al high strength stainless steel by micro-indentation and found that the loading speed had little influence on measurement, and the hardness and Young's moduli decreased with the increase of test forces. Goldbaum et al [14] used the method developed by Oliver and Pharr to analyze the indentation hardness of cold sprayed titanium coating, and proved that the defects and porosity of the coating had a significant influence on the mechanical property, especially the hardness and Young's modulus, and Ajaja et al [15] also used the method of Oliver and Pharr to determine the hardness and Young's moduli of the materials studied.…”
