Nanoindentation Mapping and Bond Strength Study of Adhesive-Dentin Interfaces

Chenmin Yao et al.

Summary: This study used scanning probe microscopy (SPM) nanoindentation technique to investigate the relationship between the structure of adhesive-dentin interfacial regions and their in situ mechanical properties. The results showed the continuous hierarchical substructures of the adhesive-dentin interfaces and a transition zone between the hybrid layer and unaffected dentin. The mechanical interlocking between intertubular dentin and adhesives was found to dominate the bond strength.

Combinatorial Investigation of the Ni-Ta System via Correlated High-Speed Nanoindentation and EDX Mapping

Jeffrey M. Wheeler et al.

Summary: The combination of correlated high-speed nanoindentation and energy-dispersive spectroscopy was successfully applied to investigate the Ni-Ta system, resolving all seven phases and determining the mechanical properties and composition ranges for each phase. A simple correlation method using overlaid data matrices allowed for easy labeling and segmentation of the data, demonstrating the potential for future research.

Mechanically alloyed high entropy alloys: existing challenges and opportunities

Akshay Kumar et al.

Summary: High entropy alloys (HEAs) were first reported in 2004, but significant progress in this field has been made since 2010 due to their unique properties and the ability to form various compositions. Researchers initially focused on equiatomic HEAs and later shifted to non-equiatomic alloys. Mechanical alloying and sintering were identified as effective methods for processing HEAs. This review discusses the properties, functional properties, and applications of mechanically alloyed HEAs, as well as the existing challenges and opportunities.

Ultra-hard, multi-phase nanocrystalline MoTa and MoTaTi based concentrated refractory alloys

Deekshith G. Kalali et al.

Summary: Binary and ternary based concentrated refractory alloys were synthesized and studied, and it was found that the BCC phase transformed into multiple phases after sintering, possibly triggered by the presence of Ti and Fe. The alloys exhibited extremely high hardness in a specific load range, with a distinct indentation size effect. Additionally, the study revealed that high end mechanical properties can be achieved without the addition of a large number of elements.

Mechanical phase mapping of the Taza meteorite using correlated high-speed nanoindentation and EDX

Jeffrey M. Wheeler

Summary: Meteorites have a unique microstructure called the Widmanstatten structure, which was mapped using mechanical phase mapping in the Taza meteorite to statistically determine properties of different phases. Five microstructural phases were identified and characterized, with mechanical phase maps showing superior contrast in two phases compared to EDX measurements.

Measurement of hardness and elastic modulus by load and depth sensing indentation: Improvements to the technique based on continuous stiffness measurement

P. Sudharshan Phani et al.

Summary: The method for measuring hardness and elastic modulus of small volumes of material through instrumented indentation was initially developed by Oliver and Pharr in their early works. This has led to advancements in the field of small scale nanomechanical testing, with improvements in measurement electronics allowing testing under a wider range of conditions. The article provides an updated overview of factors affecting precision and accuracy of nanoindentation test results, focusing on the continuous stiffness measurement technique (CSM) and presenting a step-by-step procedure for conducting CSM based tests, along with calibration procedures for optimal precision and accuracy. Additionally, an assessment and comparison of different testing procedures is presented.

Nanomechanical mapping and strain rate sensitivity of microcrystalline cellulose

Kevin M. Schmalbach et al.

Summary: Nanoindentation was utilized to study microcrystalline cellulose, revealing depth dependence of hardness and modulus attributed to material densification. The nanomechanical maps resolved void shapes and sizes in larger particles, while spatial dependence of hardness was still observed in smaller, denser particles. Hardness also changed with indentation strain rate, with resulting sensitivity values matching those from other techniques.

Alberto Orozco-Caballero et al.

Summary: A high-throughput study of local mechanical properties, chemical composition, and crystallographic orientation in cast Inconel 718 specimens revealed strong Nb segregation and its correlation with nanohardness, while indentation elastic moduli were found to be directly correlated with crystallographic grain orientation due to the high elastic anisotropy of nickel alloys.

S. Janakiram et al.

Summary: This study investigates the structure-property correlations at the micrometer length scale during recovery and early recrystallization of a cold rolled high strength steel composed of ferrite and pearlite. High resolution nano-indention mapping technique and electron microscopy were used to study the local microstructure and hardness variations with annealing temperature. A clustering algorithm was employed to determine the properties of the constituent microstructural features.

Influence of indentation size and spacing on statistical phase analysis via high-speed nanoindentation mapping of metal alloys

Hossein Besharatloo et al.

Summary: The development of high-speed nanoindentation has allowed for the acquisition of rich mechanical property data in a short amount of time, but the influences of indentation size and deconvolution method on phase properties remain unclear. By exploring different depth/spacing increments on two materials systems and comparing various statistical analyses, this study reveals the different sensitivities of deconvolution methods to errors in phase identification.
