Metadislocations in Complex Metallic Alloys
Complex Metallic Alloys (CMAs) represent a large group of crystalline intermetallics comprising some hundreds of known phases in various alloy systems. They are characterized by the presence of icosahedral atom coordination, large lattice constants, and a correspondingly large number of atoms per unit cell, typically ranging between a few tens and some thousand [1]. In recent years, CMAs have a...
متن کاملDevelopment of Metallic Sensory Alloys
Existing nondestructive evaluation (NDE) technologies are inherently limited by the physical response of the structural material being inspected and are therefore not generally effective at the identification of small discontinuities, making the detection of incipient damage extremely difficult. One innovative solution to this problem is to enhance or complement the NDE signature of structural ...
متن کاملDamping Capacity of Hypo-Eutectic Zn-Al Alloys
Damping capacity of hypo-eutectic Zn-Al alloys as a function of rolling ratio is investigated. Effect of heat treatment after cold rolling on the damping capacity is discussed. Damping tests were carried out using the method of the free decay of vibrations in bending oscillation. With an increase in rolling reduction, the damping capacity was increased. As the results of tensile and hardness te...
متن کاملA Promising New Class of High-Temperature Alloys: Eutectic High-Entropy Alloys
High-entropy alloys (HEAs) can have either high strength or high ductility, and a simultaneous achievement of both still constitutes a tough challenge. The inferior castability and compositional segregation of HEAs are also obstacles for their technological applications. To tackle these problems, here we proposed a novel strategy to design HEAs using the eutectic alloy concept, i.e. to achieve ...
متن کاملFriction and solid-solid adhesion on complex metallic alloys
The discovery in 1987 of stable quasicrystals in the Al-Cu-Fe system was soon exploited to patent specific coatings that showed reduced friction in ambient air against hard antagonists. Henceforth, it was possible to develop a number of applications, potential or commercially exploited to date, that will be alluded to in this topical review. A deeper understanding of the characteristics of comp...
