Effect of Minor Au Addition on Glass-Forming Ability and Mechanical Properties of Pd--Cu--Au--Si--P Alloys
The glass-forming ability (GFA), thermal stability and mechanical properties of bulk glassy Pd79Cu6 xAuxSi10P5 (x 1⁄4 0{6 at%) alloys were studied. The results revealed that the minor substitution of Au for Cu strongly affects the thermal stability and GFA of Pd–Cu–Au–Si–P alloys. The alloy in which 2 at% Au was added to substitute Cu (Pd79Cu4Au2Si10P5) exhibits the broadest supercooled liquid ...
متن کاملNew Pd-Based Bulk Glassy Alloys with High Glass-Forming Ability and Large Supercooled Liquid Region
With the aim of developing a new bulk glassy alloy which can be applied to biomedical applications, we examined glass-forming ability and mechanical properties of Ni-free glassy alloys in Pd50 xPtxCu30P20 system. As a result, the best glass-forming composition is located at Pd35Pt15Cu30P20, and the alloy can be formed into bulk glassy rods with diameters of up to at least 30mm by fluxed water q...
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 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...
