The alloy-design strategy of combining multiple elements in near-equimolar ratios has shown great potential for producing exceptional engineering materials, often known as ‘high-entropy alloys’. Understanding the elemental distribution, and, thus, evolution configurational entropy during solidification, is undertaken present study using Al1.3CoCrCuFeNi model alloy. Here we show that, even when material undergoes segregation, precipitation, chemical ordering and spinodal decomposition, a...
There has been considerable technological interest in high-entropy alloys (HEAs) since the initial publications on topic appeared 2004. However, only several of investigated are truly single-phase solid solution compositions. These include FCC CoCrFeNi and CoCrFeMnNi based 3d transition metals elements BCC NbMoTaW, NbMoTaVW, HfNbTaTiZr refractory metals. The search for new HEAs compositions hindered by a lack an effective scientific strategy alloy design. This report shows that chemical...
High-entropy alloys (HEAs) are a new class of solid-solution that have attracted worldwide attention for their outstanding properties. Owing to the demand from transportation and defense industries, light-weight HEAs also garnered widespread interest scientists use as potential structural materials. Great efforts been made study phase-formation rules accelerate refine discovery process. In this paper, many proposed assessed, based on series known newly-designed HEAs. The results indicate...
Abstract Severe distortion is one of the four core effects in single‐phase high‐entropy alloys (HEAs) and contributes significantly to yield strength. However, connection between atomic‐scale lattice macro‐scale mechanical properties through experimental verification has yet be fully achieved, owing two critical challenges: 1) difficulty development homogeneous solid‐solution HEAs 2) ambiguity describing related measurements calculations. A body‐centered‐cubic (BCC) refractory HEA,...
Abstract Developing affordable and light high-temperature materials alternative to Ni-base superalloys has significantly increased the efforts in designing advanced ferritic superalloys. However, currently developed still exhibit low strengths, which limits their usage. Here we use a CALPHAD-based high-throughput computational method design light, strong, low-cost high-entropy alloys for elevated-temperature applications. Through screening, precipitation-strengthened lightweight are...
The present work discovers the unique deformation behavior of a refractory high-entropy alloy at elevated temperatures.
Abstract Refractory high‐entropy alloys (RHEAs) show promising applications at high temperatures. However, achieving strengths elevated temperatures above 1173K is still challenging due to heat softening. Using intrinsic material characteristics as the alloy‐design principles, a single‐phase body‐centered‐cubic (BCC) CrMoNbV RHEA with high‐temperature (beyond 1000 MPa 1273 K) designed, superior other reported RHEAs well conventional superalloys. The origin of strength revealed by in situ...
Abstract The empirical rules for the prediction of solid solution formation proposed so far in literature usually have very compromised predictability. Some with seemingly good predictability were, however, tested using small data sets. Based on an unprecedented large dataset containing 1252 multicomponent alloys, machine-learning methods showed that solutions can be accurately predicted (93%). results help identify most important features, such as molar volume, bulk modulus, and melting...
