High‐Temperature Nanoindentation of Metals: Assessing Thermal Drift, Frame Compliance, and Chemical Composition Effects on the Reported Mechanical Properties

Advanced Engineering Materials, EarlyView.
Do not let thermal drift and instrument artifacts deceive high‐temperature nanoindentation results. We compare classical Oliver–Pharr and automatic image recognition analyses across steels and a Ni alloy to quantify these effects. Accounting for artifacts reveals systematic softening with temperature, while Cr and Ni additions boost resistance ...

Study on initial fatigue damage of magnesium alloy under torsion and bending

Nihon Kikai Gakkai ronbunshu, 2015
Torsion and bending fatigue tests of magnesium alloy AZ31were carried out to investigate the initial damage under high cycle fatigue. The crystallographic orientation of crystals in which slip lines were occurred was analyzed by using electron back ...

Creep Properties and Deformation Mechanism of Additively Manufactured NiAl‐CrMo Composites

Advanced Engineering Materials, EarlyView.
Additively manufactured NiAl‐CrMo composites contain numerous interfaces and cell boundaries that control their creep response. At 700°C under high applied stress, creep is dominated by dislocation‐controlled power‐law mechanisms. At 800°C–900°C and lower stresses, creep is primarily diffusion‐controlled along cell boundaries.

Workflow for Design of Experiments‐Based Modeling of Species Transport and Growth Kinetics in GaN Hydride Vapor Phase Epitaxy

Advanced Engineering Materials, EarlyView.
A novel workflow for investigating hydride vapor phase epitaxy for GaN bulk crystal growth is proposed. It combines Design of experiments (DoE) with physical simulations of mass transport and crystal growth kinetics, serving as an intermediate step between DoE and experiments.

Dynamic Earthquake Ruptures in the Presence of Material Discontinuities [PDF]

, 2009
A general feature of tectonic faults is the juxtaposition of materials with dissimilar elastic properties in a variety of contexts and scales. Normal and reverse faults offset vertical stratifications, large strike-slip faults displace different crustal ...
