Nanotechnologies have already attracted massive interest in multiple fields of science and industry. In the past decades, we have witnessed the progress in micro-level experimental techniques that revolutionize the material science. Designing new materials based on the knowledge of mechanics of their building blocks and microstructure manipulations at nanometer scale have become a reality. Nanoindentation, as a leading micro-level mechanical testing technique, has attracted wide attention in numerous research fields and applications. Nowadays, an extensive variety of testing areas ranging from classical thin coatings in machinery engineering, electronics and composites to far fields of civil engineering, biomechanics, implantology or even agriculture can be covered with this universal testing tool. The book aims to be a walk through achievements in some of the distant fields and to give a brief overview of the current frontiers in nanoindentation. Although it is not possible to cover the whole width of the possible themes in one book, it is believed that the reader will benefit from the topics variety and the book will serve as a useful source of literature references.

These proceedings of the November 2007 symposium include a range of papers in these dynamic disciplines within materials science. Evolving and complementary, nanoindentation and nanotribology substantially add to the evidence that biomechanical research has caused a number of disciplines to overlap. In addition, researchers are finding new mechanical tests that can measure smaller and smaller forces and displacements. This situation is reflected in the 27 papers with general topics including the relation among nanomechanics, tribology and nanostructures; size effects and indentation of thin films (including an invited paper on the mechanical properties of 3C-SiC films for MEMS applications); nanotribology and friction (with an invited paper on quasi-static and oscillatory indentation in linear viscoelastic solids); and nanome-chanics of polymers in time-dependent characterization.

Austenitic stainless steel, hard-facing alloys have recently been developed as a replacement to the cobalt-based Stellite alloys traditionally used for valve seat coatings in the nuclear power industry. NitroMaxx, a new nitrogen-saturated stainless steel, has proven capable of overcoming the performance degradation issues seen in other austenitic stainless steels at high temperatures (~350°C). NitroMaxx's excellent galling-resistance has, in part, been attributed to a stacking fault energy (SFE) modification brought about by the addition of interstitial nitrogen. To better understand the matrix-specific mechanical properties that processing parameters affect and to develop a cost and time efficient screening tool for future alloy development, nanoindentation and post-indentation analysis was performed. Nanoindentation was used to obtain both composite and matrix-specific mechanical properties. The indents were subjected to post-indentation topographical analysis with an optical profilometer and an atomic force microscope (AFM). Scanning electron microscopy coupled with electron backscatter diffraction (EBSD) provided crystallographic information and further deformation characterization.

Degradation processes of structural materials for Gen-4 nuclear reactors include irradiation hardening, irradiation-assisted stress-corrosion cracking and embrittlement. Techniques for investigation of materials have been developed to identify the effects of irradiation on a materials microstructure and mechanical properties. Nanoindentation measurements provide information about the elastic-plastic properties of materials. Nanoindentation hardness measurement can also be used to determine the yield strength of materials. The analysis of neutron irradiated materials is sophisticated process in terms of safety since these materials are activated. Ion irradiation serves as a substitute for neutron irradiation. If irradiation is performed properly, it can provide similar microstructure to what observed after neutron irradiation. As a result, ion irradiation analysis has been widely used to provide information about materials microstructure in irradiation environment. This work characterizes the mechanical properties of ion irradiated model alloy 21Cr32Ni and commercial alloy 800H. Nanoindentation technique was applied to two different geometric configurations for each alloy to investigate how irradiation affects the hardness and reduced modulus. The surface nanoindentation presents the hardness and reduced modulus measurements when measured along the ion irradiation. In contrast, cross-section nanoindentation measurements show the hardness and reduced modulus at 7-20 degrees tilted relative to the irradiated surface. A matrix of indents was performed on specific grain orientations that provide the dependence of hardness on crystal orientation. The specific grain orientations were determined using Electron Backscatter Diffraction. Three main grain orientations 111, 101 and 001 were analyzed. The relationship between grain orientation, hardness and reduced modulus was tested in irradiated and non-irradiated alloys. The yield strength can be determined from measurement of the penetration depth, according to the indentation size effect. The hardness can be used to calculate the yield strength through an empirical formula. Additionally, Transmission Electron Microscopy images of the microstructure provide information on faulted loops that can be utilized through the Orowan hardening model to calculate the yield strength. In addition, the results of yield strength serve as identification for the saturation level of irradiation hardening.

The directed assembly of nanoscale components has the potential to generate novel macroscopic materials with specific hierarchically ordered structures and programmable physical and chemical properties. DNA is a particularly promising material to direct nanomaterial assembly, as its sequence-specific complementary binding allows DNA to be used to precisely tailor interactions between a multitude of different nanoscale elements, allowing formation of complex nanoscale structures without top-down instruction. While multiple DNA-based materials assembly methods have been developed, the mechanical properties of many of these systems are unknown due to limitations in both the preparation of materials suitable for mechanical testing and difficulties in measuring the behavior of these soft materials under applied force. The modulus of one particular architecture - DNA-NP superlattices - is studied here by first examining methods to create thin films of DNA-NPs that can be accurately probed using nanoscale mechanical testing techniques, then using AFM nanoindentation of various superlattice designs to correlate DNA-NP lattice structure to mechanical behavior. A layer-by-layer deposition strategy was first examined in order to understand how deposition conditions affect the packing density and surface roughness of thin films of DNA-NPs as a function of deposition time, bulk system temperature, and solution ionic strength. Subsequent experiments used a slow-cooling method to generate single crystal superlattice architectures, where the size and shape of the substrate-bound crystals could be tailored by tuning the relative strength of the interactions between the substrate and DNA-NPs, and could be described by the Winterbottom construction. Additionally, FCC single crystal structures were demonstrated, which have not been previously shown in literature. Using the substrate-bound crystals, the dependence of the modulus on DNA length, nanoparticle size, and density of DNA strands was determined, which allowed for the establishment of design rules that will ultimately enable control over the mechanical properties of future DNA-based nanoparticle structures.
