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

International 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 °

State-of-the-Art Design and Optimization of Strain Gauge-Type Load–Displacement Transducer for in In Situ Nanoindentation Systems

Sensors
Force–displacement transducers are key components in in situ nanoindentation systems. The current existing capacitance-type transducers adopted in state-of-the-art commercial in situ nanoindentation systems are restricted by limited maximum ranges, and ...

Mechanical properties of collagen fibrils [PDF]

, 2007
The formation of collagen fibers from staggered subfibrils still lacks a universally accepted model. Determining the mechanical properties of single collagen fibrils ( diameter 50 - 200 nm) provides new insights into collagen structure. In this work, the

Practical method to determine the effective zero-point of indentation depth for continuous stiffness measurement nanoindentation test with Berkovich tip

Scientific Reports, 2022
The zero-point of indentation depth in nanoindentation or depth-sensing instrumented indentation tests should be precisely set to evaluate the indentation hardness and indentation elastic modulus of materials to be tested, especially at shallow depths. A

Quantitative approach to determine the mechanical properties by nanoindentation test: Application on sandblasted materials [PDF]

, 2015
A novel method is developed to improve the accuracy in determining the mechanical properties from nanoindentation curves. The key point of this method is the simultaneous statistical treatment of several loading curves to correct the zero point error and

A Lightweight Procedural Layer for Hybrid Experimental–Computational Workflows in Materials Science

Advanced Engineering Materials, EarlyView.
We unveil a prototype hybrid‐workflow framework that fuses automatedcomputation with hands‐on experiments. Built atop pyiron, a lightweight, parameterized layer translates procedure descriptions into executable manual steps, syncing instrument settings, human interventions, and data capture in real‐time today.

Determination of elastic moduli of elastic–plastic microspherical materials using nanoindentation simulation without mechanical polishing

Beilstein Journal of Nanotechnology, 2021
When using the Oliver–Pharr method, the indented specimen is assumed to be a perfectly flat surface, thus ignoring the influences of surface roughness that might be encountered in experiment. For nanoindentation measurements, a flat surface is fabricated

Quantifying delamination energy in tungsten on silicon thin films through nanoindentation and nanoscratch

Materials & Design
Quantifying delamination energy is crucial for the reliability and longevity of thin films. In this work, the delamination energy in tungsten-silicon thin films is investigated through nanoindentation and nanoscratching. Nanoindentation was also employed
