Beyond Indentation Hardness and Modulus: Recent Advances in Nanoindentation Techniques: Part I

JOM Beyond Indentation Hardness and Modulus: Recent Advances in Nanoindentation Techniques: Part I XINGHANG ZHANG 0 0 1.-State Key Lab of Metal Matrix Composites, School of Materials Science and Engineering, Shanghai Jiao Tong University , Shanghai 200240 , People's Republic of China. 2.-School of Materials Engineering, Purdue University , West Lafayette, IN 47907, USA. 3.- - YUE LIU Instrumented indentation testing has long been used for determining hardness and modulus at submicrometer-length scales. Recently, advances in indentation-based mechanical testing have enabled quantitative characterization of more complex mechanical behaviors at the nanoscale, such as stress–strain relation, visco-elastic/plastic property, creep and stress relaxation behavior, strain-rate sensitivity, fracture toughness, interfacial adhesion, and in situ nanoindentation in electron microscopes. The ability to characterize quantitatively and tailor the mechanical properties of individual microstructures/phases/constituents/interfaces in bulk materials at the nanoscale, as well as thin films and lowdimensional materials, has been critical for making revolutionary advances in materials development. The scope of Part I of this JOM special topic is to review some of these recent advances in nanoindentation techniques on measuring various nanoscale mechanical properties. The topic will continue with Part II scheduled to publish in early 2018. Recently the measurement of the creep response of materials at small scales has received renewed interest. Despite an increasing capability to perform high-temperature nanomechanical testing on advanced instrument, several significant experimental and modeling challenges remain in smallscale mechanical testing at elevated temperatures. In this regard, relating the creep response probed by high-temperature instrumented indentation experiments to macroscopic uniaxial creep response is of great practical value. The article titled ‘‘On the Measurement of Power Law Creep Parameters from Instrumented Indentation’’ by Sudharshan Phani et al. reviews various methods currently being used Yue Liu and Xinghang Zhang are the JOM advisors for the Nanomechanical Materials Behavior Committee of the TMS Materials Processing and Manufacturing Division, and guest editors for the topic Beyond Indentation Hardness and Modulus: Advances in Nanoindentation Techniques: Part I in this issue. to measure creep with instrumented indentation, with a focus on geometrically self-similar indenters, and their relative merits and demerits from an experimental perspective. Additionally, a comparison of various methods that use instrumented indentation results to predict the uniaxial power law creep response of a wide range of materials is presented to assess their validity. Instrumented indentation or nanoindentation can also be employed to measure thin film interfacial adhesion energies by producing well-defined areas of delamination. When combined with the proper mechanics-based model and characterization of the failing interfaces, nanoindentation induced delamination becomes a powerful tool to quantify interfacial fracture properties. The review article on ‘‘New Insights into Nanoindentation-Based Adhesion Testing’’ by Kleinbichler et al. presents new development of the technique, which was first introduced by Marshall and Evans in the 1980s. The improvements are demonstrated using a WTi/Si3N4 film system on a rigid silicon wafer where the WTi acts as a stressed overlayer. Furthermore, focused ion beam cross-sectioning and confocal laser scanning microscopy were used to characterize failing interfaces and additional fracture events, as well as to determine the adhesion energy. By adapting standard nanoindentation test methods, simple protocols capable of probing thermally activated deformation processes can be accomplished. Abrupt strain-rate changes within one indentation allow the determination of the strainrate dependent variation of hardness at various indentation depths. To exclude thermal drift at low strain rates, long-term creep experiments can be performed by using the dynamic contact stiffness for determining the true contact area. From both procedures, hardness and strain-rate, and consequently strain-rate sensitivity and activation volume, can be reliably deducted within one Liu and Zhang effects and microstructure evolution during nanoindentation tests and create a unique opportunity for establishing new calibration procedures to nanoindentation techniques.
