Fracture resistance of high entropy alloys: A review 3 Fractographic characteristics Visually examining the fracture surfaces of failed HEAs is a straightforward means to study their fracture modes, thereby gaining insights on microscopic deformation mechanisms responsible for high or low fracture toughness...
To comprehensively understand the fracture mechanisms, material properties, root causes of failure, and the subsequent optimization of alloys, a detailed analysis of the internal fracture process and the morphological traits of the fracture surface is imperative. Traditional analysis of fracture surfaces ...
Not only in metals or conventional binary or ternary alloys but also in a multi-component high-entropy alloy (HEA) - CrMnFeCoNi - the nano-scale twins have been observed to delay the onset of any necking instability including the localized plastic deformation that could lead to premature ...

Microstructure and mechanical properties of the CrMnFeCoNi highentropy alloy. (A) Fully recrystallized microstructure with an equiaxed grain structure and grain size of ~6 mm; the composition is approximately equiatomic, and the alloy is single-phase, as shown from the EDX spectroscopy and XRD inset...
Several approaches have been proposed to determine the mechanical properties of 2D materials. Deflection of suspended graphene membranes has generally been performed using an atomic force microscope tip6, which, when applied to chemical vapor deposition (CVD)-graphene indicated a strength reduction by 40...
been found that the plastic strain induced by recrystallization nucleation and growth at the original high angle grain boundary (HAGB) of the alloy is not enough to coordinate the rotation of the original grain and the sliding of the original HAGB during deformation, resulting in intergranular ...
The high hardness values for nc-W are explained by the fact that W possesses a large Hall-Petch coefficient [3]. The properties of W are not only dependent on the microstructure but are also influenced by p-block impurities (< 1 at.%), which can be incorporated into the material during...
