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 کاملComplex metallic alloys as new materials for additive manufacturing
Additive manufacturing processes allow freeform fabrication of the physical representation of a three-dimensional computer-aided design (CAD) data model. This area has been expanding rapidly over the last 20 years. It includes several techniques such as selective laser sintering and stereolithography. The range of materials used today is quite restricted while there is a real demand for manufac...
متن کاملProperties- and applications of quasicrystals and complex metallic alloys.
This article aims at an account of what is known about the potential for applications of quasicrystals and related compounds, the so-called family of Complex Metallic Alloys (CMAs‡). Attention is focused at aluminium-based CMAs, which comprise a large number of crystalline compounds and quasicrystals made of aluminium alloyed with transition metals (like Fe or Cu) or normal metals like Mg. Depe...
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...
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 ...
