Evaluation of thin film material properties using a deep nanoindentation and ANN

open access: yesMaterials & Design, 2022
Due to the substrate effect, there are several difficulties to evaluate the material properties of thin films via nanoindentation. In this study, an inverse analysis method based on an artificial neural network (ANN) is proposed to obtain free-volume ...

Osteoarthritis severely decreases the elasticity and hardness of knee joint cartilage: A nanoindentation study [PDF]

open access: yes, 2019
The nanoindentation method was applied to determine the elastic modulus and hardness of knee articular cartilage. Cartilage samples from both high weight bearing (HWB) and low weight bearing (LWB) femoral condyles were collected from patients diagnosed ...

Measurement of Elastic Properties of Brittle Materials by Ultrasonic and Indentation Methods

open access: yesApplied Sciences, 2019
The measurements of acoustic properties of three brittle materials i.e., ITO (alkaline earth boro-aluminosilicate) glass, bulk metallic glass (BMG) and nickel-based superalloy (CM247LC) are conducted in this work to obtain various properties. The elastic

Small scale fracture behaviour of multilayer TiN/CrN systems: Assessment of bilayer thickness effects by means of ex-situ tests on FIB-milled micro-cantilevers [PDF]

open access: yes, 2016
TiN/CrN multilayered PVD coatings are known to exhibit outstanding micromechanical properties and wear resistance. On the other hand, information on their small scale fracture behaviour is rather scarce.

Characterization and analysis of hot compression behaviors of an ultralight Mg-Li-Al alloy

open access: yesInternational Journal of Lightweight Materials and Manufacture, 2019
This paper aims at establishing microstructure/property/processing correlations in a thermomechanically processed ultralight Mg-3.5Li-1Al (wt%) alloy. The thermomechanical cycle consists of uniaxial compression at temperatures of 250 °C, 350 °C, and 450 °
