Disordered materials, like metallic glasses or silicate glasses, have an atomistic amorphous
structure preventing the formation of extended defects such as dislocations. Irreversible …

The multi-principal-component concept of high-entropy alloys (HEAs) generates numerous
new alloys. Among them, nanoscale precipitated HEAs have achieved superior mechanical …

Pre-strain is often used as a powerful pre-treatment to tailor the microstructures and
mechanical properties of traditional alloys. However, in high-entropy alloys (HEAs), the …

We propose a method for nondestructive characterization of progressive fatigue damage in
solid plates, using a zero-group-velocity (ZGV) Lamb mode generated and detected by …

Dislocation engineering has the potential to open new avenues toward the exploration and
modification of the properties of quantum materials. Strontium titanate (SrTi O 3, STO) and …

In this paper, a non-contact non-destructive evaluation of cumulative fatigue damage in 75 μ
m-thick aluminum plates is conducted by using the first symmetric zero-group-velocity Lamb …

Shot peening has traditionally been thought to improve the fatigue performance of
polycrystalline nickel-based superalloys by inducing a compressive residual stress at the …

Superduplex stainless steels (SDSSs) have high mechanical and corrosion resistance.
Those properties are due to the biphasic microstructure formed by ferrite and austenite in …

Ultrasound has long been used as a non-destructive tool to test for the brittle fracture of
materials. Could it be used as a similar tool to test for ductile failure? As a first step towards …

The jerky flow phenomenon, called the Portevin–Le Chatelier (PLC) effect, is one of the most
investigated problems of plastic deformation. However, experimental and theoretical …
