A group of scientists has printed a nanoalloy that is superior in strength and ductilityOthers additively
High-entropy alloys over the past 15 yearsare becoming more and more popular. They are made up of five or more elements in nearly equal proportions and can be used in an infinite number of unique combinations for alloy development. And traditional alloys such as brass, stainless steel, carbon steel, and bronze contain a base element combined with one or more trace elements.
new material
Scientists have combined the method of producing alloys withmodern 3D printing technology to develop new materials with unique properties. Since the materials melt and solidify very quickly in this process compared to traditional metallurgy, a very different microstructure is obtained. It looks like a network and consists of alternating layers.
"The restructuring of this unusual microstructureresults in ultra-high strength as well as increased ductility, which is rare since normally strong materials tend to be brittle,” the researchers note.
Ability to produce strong and toughmaterials means that these 3D printed materials are more reliable in resisting deformation, which is important for designing lightweight structures to improve mechanical efficiency and save energy.
