Microwave-Assisted Preparation of High Entropy Alloys [PDF]

open access: yes, 2015
Microwaves at the ISM (Industrial, Scientific and Medical, reserved internationally) frequency of 2450 or 5800 MHz have been used to prepare FeCoNiCuAl, FeCrNiTiAl and FeCoCrNiAl2.5 high entropy alloys by direct heating of pressed mixtures of metal ...

Nanoprecipitate‐Strengthened High‐Entropy Alloys

open access: yesAdvanced Science, 2021
Multicomponent high‐entropy alloys (HEAs) can be tuned to a simple phase with some unique alloy characteristics. HEAs with body‐centered‐cubic (BCC) or hexagonal‐close‐packed (HCP) structures are proven to possess high strength and hardness but low ...

Dynamic response of high-entropy alloys to ballistic impact

open access: yesScience Advances, 2022
High-entropy alloys (HEAs) are promising to provide effective antiballistic capability because of their superior mechanical properties. However, the twinning-active Cantor alloy is found less ballistic resistant, compared with its Mn-free companion.

Mechanistic origin of high retained strength in refractory BCC high entropy alloys up to 1900K

open access: yes, 2019
The body centered cubic (BCC) high entropy alloys MoNbTaW and MoNbTaVW show exceptional strength retention up to 1900K. The mechanistic origin of the retained strength is unknown yet is crucial for finding the best alloys across the immense space of BCC ...
