Glassy Pd85 xCuxSi10P5 (x 1⁄4 5{12 at%) alloys with a supercooled liquid region ( Tx) of 51–73K were synthesized despite the low metalloid content. The glassy Pd79Cu6Si10P5 alloy exhibits the largest Tx of 73K in the present alloy system and its critical diameter for glass formation reaches 5mm by copper mold casting. For the bulk glassy Pd79Cu6Si10P5 alloy, the Young’s modulus, compressive yie...

Kodkod, the backend of Alloy4, incorporates new features for solving models where part of the solution, that is, a partial instance, is already known. Although Kodkod has had this functionality for some time, it is not explicitly available to the modeller through the Alloy language syntax. We propose an extension to the Alloy language to make partial instances explicitly available to the Alloy ...

During the second half of the twentieth century, algebraic methods have been increasingly recognised as powerful approaches to the formalisation of musical structures. This is evident in the American music-theoretical tradition as well as in the European formalised approach to music and musicology. We mention the mathematician and composer Milton Babbitt, the Greek composer Iannis Xenakis and t...

The fatigue strength, effects of a notch on the fatigue strength, and fatigue crack growth rate of Ti-15Zr-4Nb-4Ta alloy were compared with those of other implantable metals. Zr, Nb, and Ta are important alloying elements for Ti alloys for attaining superior long-term corrosion resistance and biocompatibility. The highly biocompatible Ti-15Zr-4Nb-4Ta alloy exhibited an excellent balance between...

In this study, the pitting corrosion susceptibility and its role on the hydrogen embrittlement behavior of AZ80 magnesium alloy were studied using slow strain rate testing (SSRT), electrochemical technique and immersion test method. The electrochemical and immersion tests in chloride-containing solution revealed severe pitting corrosion in the alloy. The SSRT results of the alloy under continuo...

A method is presented to use a dimensionless form of the well-known Niyama criterion to directly predict the amount of shrinkage porosity that forms during solidification of metal alloy castings. The main advancement offered by this method is that it avoids the need to know the threshold Niyama value below which shrinkage porosity forms; such threshold values are generally unknown and alloy dep...

The flexural strength and flexural modulus of an experimental metal-resin composite, which used Ag-In alloy particle as the filler, were evaluated. The effect of acid treatment and heat treatment on the Ag-In alloy particle was investigated. The flexural strength of the experimental metal-resin composites ranged from 65.5 MPa to 91.0 MPa. The flexural strength of the metal-resin composite incre...

Ti and Ti‒5wt% W alloy foams were produced by freeze-casting process and their mechanical behaviors were compared. The Ti‒5W alloy foam showed a typical acicular Widmanstätten α/β structure with most of the W dissolved in the β phase. An electron-probe microanalysis revealed that approximately 2wt% W was uniformly dissolved in the Ti matrix of Ti‒5W alloy foam with few partially dissolved W par...

Scatter behavior of fatigue life in die-cast AM60B alloy was investigated. For comparison, those in rolled AM60B alloy and die-cast A365-T5 aluminum alloy were also studied. Scatter behavior of pore size was also investigated to discuss dominant factors for fatigue life scatter in die-cast materials. Three-parameter Weibull function was suitable to explain the scatter behavior of both fatigue l...

Tuning the enzyme-like activity and studying the interaction between biologically relevant species and nano-enzymes may facilitate the applications of nanostructures in mimicking natural enzymes. In this work, AuPt alloy nanoparticles (NPs) with varying compositions were prepared through a facile method by co-reduction of Au3+ and Pt2+ in aqueous solutions. The composition could be tuned easily...
