Scientists create titanium parts using additive technologies

Manufacturing products from titanium and its alloys using traditional methods remains a complex technological task that requires a lot of time and money. Scientists at South Ural State University have developed a new universal ...

Making new catalysts from unique metallic alloys

Heusler alloys are magnetic materials made from three different metals that are not magnetic individually. The alloys are used broadly for their magnetic and thermoelectric properties, and their ability to regain their original ...

Adding copper strengthens 3-D-printed titanium

Successful trials of titanium-copper alloys for 3-D printing could kickstart a new range of high-performance alloys for medical device, defence and aerospace applications.

An alloy that retains its memory at high temperatures

Using computer simulation, Alberto Ferrari calculated a design proposal for a shape memory alloy that retains its efficiency for a long time even at high temperatures. Alexander Paulsen manufactured it and experimentally ...

Additive manufacturing and Ni/Ti metal bolster cooling technology

Scientists at the University of Maryland (UMD) have developed a novel elastocaloric cooling material, comprised of a nickel (Ni)-titanium (Ti) alloy and sculpted using additive technology, that is highly efficient, eco-friendly ...

Making metallic materials more climate-friendly

Six percent of global CO2 emissions—4.4. billion tonnes per year—are currently produced by the steel and aluminum industry. In an overview article for the journal Nature, Dierk Raabe, Director at the Max-Planck-Institut ...

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.
