Behind every aircraft, turbine, and high-load structure is a steel alloy doing the heavy lifting. Advanced high-performance alloys are critical for their function. Image Credit: ...

In its purest form, iron is neither exceptionally strong nor hard - in fact, a block of pure iron could be cut with a knife. The addition of carbon and the removal of oxygen are what give iron-based ...

Steels that contain specified amounts of alloying elements -- other than carbon and the commonly accepted amounts of manganese, copper, silicon, sulfur, and phosphorus -- are known as alloy steels.

Metals used for steel alloys, once considered the poor cousins to iron ore, are starting to come into vogue, with both big and small players moving heaven and earth to uncover the next big discovery ...
