Subtyping in alloy
A type system for the Alloy modelling language is described that supports subtypes and allows overloading of relation names. No special syntactic features needed to be added to the language to support the type system; there are no casts, and the meaning of a model can be understood without …

High temperature creep-fatigue behavior of alloy 617 and alloy 230
… applications. Currently, Ni-based superalloy alloy 617 (Inconel 617) and alloy 230 (Haynes 230) are considered as the leading metallic candidate materials for applications in the VHTR because of their favorable mechanical properties at elevated temperatures. The major damage mechanism …

The vanadium-zirconium alloy system
<p>This investigation of the vanadium-zirconium alloy system produced evidence on several points concerning the equilibrium diagram. It was shown that a eutectic reaction between an intermediate phase and a zirconium-rich solid solution occurs at a temperature of 1230° +/- 10°C, and that the …

Translating alloy using Boolean circuits
Alloy is a automatically analyzable modelling language based on first-order logic. An Alloy model can be translated into a Boolean formula whose satisfying assignments correspond to instances in the model. Currently, the translation procedure mechanically converts each piece of the Alloy model …

Zinc alloy powders for alkaline batteries
… gas as a byproduct. In the past, mercury was alloyed with zinc to slow down the corrosive process and prevent excessive hydrogen generation. Since mercury has been deemed as a health and environmental hazard, bismuth and indium are now used as alloying elements to suppress hydrogen evolution. …

Reduction expansion synthesis for magnetic alloy powders
… scale ferromagnetic and magnetic rare-earth alloys were produced using Reduction Expansion Synthesis (RES), a technique in which metal particles are the product of the rapid heating to approximately 800 degrees Celsius, in inert atmosphere, of physical mixtures of urea, or similar molecules, …

Revisiting the theory of alloy thermal conductivity
… waves. For example, the phonon contributions to alloy thermal conductivity rely on this assumption and are most often computed from the virtual crystal approximation (VCA). In this dissertation, we show that the conventional theory and understanding of phonons requires revision, because the …
