Conventional alloys have one principal element, with minor modifications achieved by adding relatively small amounts of other elements. As many as a dozen other elements may be added, but conventional ...

Researchers at the University of Massachusetts and the University of Pennsylvania successfully synthesized a multiscale multi-principal element alloy (MPEA) composed of Ni, Fe, and Mn, through an ...

Alchemy, which attempted to turn cheap metals such as lead and copper into gold, has not yet succeeded. However, with the development of alloys in which two or three auxiliary elements are mixed with ...
