Using viscous metals in micro fibers

EPFL scientists have developed the first micro-structured fibers with a viscous metal insideā€”a perfect example of what cross-disciplinary teamwork can achieve.

Discovery of disordered nanolayers in intermetallic alloys

Intermetallic alloys potentially have high strength in a high-temperature environment. But they generally suffer poor ductility at ambient and low temperatures, hence limiting their applications in aerospace and other engineering ...

Research team proposes technology for producing superplastic wire

Currently, low-alloy aluminum is widely used in electrical engineering and machine building. At the same time, it should be noted that modern electrical engineering places very high and in some cases mutually exclusive requirements ...

Precise magnets 3-D printed from special stainless steel

It looks quite inconspicuous to the casual beholder, hardly like groundbreaking innovation: a small metallic chessboard, four millimeters long on either side. At first glance, it shines like polished steel; at second glance, ...

Physicists test titanium target windows for particle beam

In the late 2020s, Fermilab will begin sending the world's most intense beam of neutrinos through Earth's crust to detectors in South Dakota for the international Deep Underground Neutrino Experiment, or DUNE. When the new ...

Alloy

An alloy is a mixture or metallic solid solution composed of two or more elements. Complete solid solution alloys give single solid phase microstructure, while partial solutions give two or more phases that may or may not be homogeneous in distribution, depending on thermal (heat treatment) history. Alloys usually have different properties from those of the component elements.

Alloy constituents are usually measured by mass. Alloys are usually classified as substitutional or interstitial alloys, depending on the atomic arrangement that forms the alloy. They can be further classified as homogeneous, consisting of a single phase, heterogeneous, consisting of two or more phases, or intermetallic, where there is no distinct boundary between phases.
