Entropy‐Driven Design of Low‐Melting‐Point Alloys via Compositionally Complex Strategy
Advanced Engineering Materials, EarlyView.Conventional low‐melting‐point alloys (LMPAs) are limited by a narrow compositional space and inherent property trade‐offs. This review presents an entropy‐driven design strategy that overcomes these limitations, ushering in a new class of low‐melting‐point compositionally complex alloys (LMCCAs).

Static-to-sliding friction measurements
, 2012 Static friction is a phenomenon mainly regarded as related to frictional joints within static mechanics. At the onset of sliding in mechanical contacts, static friction determines the initial resistance against motion, which subsequently is superseded by

Advanced Engineering Materials, EarlyView.CT‐based finite element simulations combined with in situ X‐ray computed tomography are used to analyze insert pull‐out in nickel‐coated polymer foams. Despite variations in material parameters, deformation consistently concentrates within a narrow annular region around the insert.

Relationship between contact size and static friction: An approach for rigid crystalline surfaces
Friction, 2020 Relationship between contact size (A) and static friction (f) has been studied for rigid crystalline systems. We built a series of systems with two identical surfaces but different orientations and investigated the effects of the size and shape of the ...

Demo 03-05 Surface Dependence of Friction
, 2001 This demonstration illustrates that the frictional force between different surfaces is very different. Four identical brass blocks are placed on strips of four different materials, and one end of the device is raised, as indicated in Figure 1, until ...

Advanced Engineering Materials, EarlyView.HEA interlayers offer a versatile route for joining high‐performance structural materials. Their compositional and structural design regulates interfacial reactions, suppresses brittle IMCs, and improves metallurgical bonding. Sandwich interlayers further integrate defect healing with precipitation strengthening, enabling improved strength–ductility ...

Effects of surface structure deformation on static friction at fractal interfaces [PDF]
, 2013 The evolution of fractal surface structures with flattening of asperities was investigated using isotropically roughened aluminium surfaces loaded in compression. It was found that asperity amplitude, mean roughness and fractal dimension decrease through
