Conventional alloys are usually based on a single host metal. Recent high-entropy alloys (HEAs), in contrast, employ multiple principal elements. The strength of HEAs is considerably higher than ...

Zhaoxuan Wu and William Curtin of the Laboratory for Multiscale Mechanics Modeling (LAMMM) have solved the 40-year-old scientific riddle of the low ductility magnesium. Magnesium is the lightest metal ...

A research team co-led by materials scientists from City University of Hong Kong (CityU) has recently discovered a new mechanism to increase the strength and ductility of a high-entropy alloy, two ...

To understand better the statistics of this occupation difference between oxygen and nitrogen, we conducted internal-friction measurements on both interstitial alloy variants O-2 and N-2 HEAs; see ...

A new technique from Purdue University is designed to improve missiles, engines and drinking glasses made from ceramic materials. (Stock photo) Something as simple as an electric field could soon make ...

Thanks to a new strategy in the development of materials related to steel, high strength and ductility are no longer mutually exclusive. For the steel industry, there may be a way out of the dilemma ...

The deep cryogenic treatment + laser shock peening produces gradient heterogeneous structures, as well as the multiple effects of heterodeformation-induced hardening, transformation-induced plasticity ...

A new chromium-molybdenum-silicon alloy has overcome a decades-old trade-off between strength and stability. The alloy, developed by German researchers, has a rare combination of ductility at room ...

Strength and flexibility are two opposites that usually need to be balanced in steel. But now engineers at Purdue University and Sandia National Labs have developed a new treatment that can be applied ...

Carbon steel is an iron-carbon alloy. Although pure iron is not intrinsically strong, adding carbon imparts great strength to this material. Crude iron, which is used in steel production, has a high ...

Materials scientists have recently discovered a new mechanism to increase the strength and ductility of a high-entropy alloy, two properties which normally vary inversely with each other. The findings ...
