Unusual glass-forming ability of bulk amorphous alloys based on ordinary metal copper.
We report the unusual glass-forming ability (GFA) of a family of Cu-based alloys, Cu46Zr47-xAl7Yx (0<x< or =10, in at. %), and investigate the origin of this unique property. By an injection mold casting method, these alloys can be readily solidified into amorphous structures with the smallest dimension ranging from 4 mm up to 1 cm without detectable crystallinity. Such superior GFA is found pr...
متن کاملThermodynamics and the Glass Forming Ability of Alloys
Bulk metallic glasses (BMGs) have received a great deal of attention due to scientific and technological interest ever since the first successful synthesis of an amorphous phase in the Au–Si system in 1960 (Klement et al., 1960). There has been a lot of interest to identify parameters to assess the glass forming ability (GFA) of various alloy systems and compositions. A great deal of scientific...
متن کاملOn the glass forming ability of liquid alloys.
By using the concepts of the short-range order (SRO) and middle-range order (MRO) characterizing structures, an attempt has been made to describe the glass forming ability (GFA) of liquid alloys. This includes the effect of more than two kinds of SRO in the liquid caused by the addition of second and third elements to a metallic solvent. The minimum solute concentration is related to the atomic...
متن کاملThe glass-forming ability of model metal-metalloid alloys.
Bulk metallic glasses (BMGs) are amorphous alloys with desirable mechanical properties and processing capabilities. To date, the design of new BMGs has largely employed empirical rules and trial-and-error experimental approaches. Ab initio computational methods are currently prohibitively slow to be practically used in searching the vast space of possible atomic combinations for bulk glass form...
متن کاملElectrochemical properties of bulk glass-forming Zr-based alloys
tive high potential for applications. Bulk amorphous Zr-based alloys exhibit interesting mechanical properties, i.e. extremely high yield strength combined with a relatively low Young’s modulus at ambient temperatures as well as Newtonian flow in the supercooled liquid state [3]. However, applications of these materials require also high stability in various environments in order to ensure an a...
