The degree of order/disorder can be measured by entropy, and it can be divided into two parts: topological disordering and chemical disordering. The former mainly refers to order in the spatial configuration, e.g., amorphous alloys which show short-range ordering but without long-range ordering, while the latter mainly refers to the order in the chemical occupancy, that is to say, the components can replace each other, and typical representatives are high-entropy alloy (HEAs). HEAs, in sharp contrast to traditional alloys based on one or two principal elements, have one striking characteristic: their unusually high entropy of mixing. They have not received much noticed until the review paper entitled “Microstructure and Properties of High-Entropy Alloys” was published in 2014 in the journal of Progress in Materials Science. Numerous reports have shown they exhibit five recognized performance characteristics, namely, strength–plasticity trade-off breaking, irradiation tolerance, corrosion resistance, high-impact toughness within a wider temperature range, and high thermal stability. So far, the development of HEAs has gone through three main stages: 1. Quinary equal-atomic single-phase solid solution alloys; 2. Quaternary or quinary non-equal-atomic multiphase alloys; 3. Medium-entropy alloys, high-entropy fibers, high-entropy films, lightweight HEAs, etc. Nowadays, more in-depth research on high-entropy alloys is urgently needed.Research & information: generalbicsschigh-entropy alloysalloys designlightweight alloyshigh entropy alloyselemental additionannealing treatmentmagnetic propertymicrohardnessin situ X-ray diffractiongrain refinementthermoelectric propertiesscandium effectHEAhigh-entropy alloyCCAcompositionally complex alloyphase compositionmicrostructurewear behaviourmetal matrix compositesmechanical propertieshigh-entropy filmsphase structureshardnesssolid-solutioninterstitial phasetransmission electron microscopycompositionally complex alloysCrFeCoNi(Nb,Mo)corrosionsulfuric acidsodium chlorideentropymulticomponentdifferential scanning calorimetry (DSC)specific heatstacking-fault energydensity functional theorynanoscaled high-entropy alloysnanodisturbancesphase transformationsatomic-scale unstablemechanical alloyingspark plasma sinteringnanoprecipitatesannealingphase constituention irradiationhardening behaviorvolume swellingmedium entropy alloyhigh-pressure torsionpartial recrystallizationtensile strengthhigh-entropy alloys (HEAs)phase constitutionmagnetic propertiesCurie temperaturephase transitionprecipitationstrengtheningcoherent microstructureconventional alloysnanocrystalline materialshigh entropy alloysputteringdeformation and fracturestrain rate sensitivityliquid phase separationimmiscible alloysHEAsmulticomponent alloysmiscibility gapsmulti-principal element alloysMPEAscomplex concentrated alloysCCAselectron microscopyplasticity methodsplasticityserration behavioralloy designstructural metalsCALPHADsolid-solution alloyslattice distortionphase transformation(CoCrFeNi)100−xMox alloyscorrosion behaviorgamma double prime nanoparticleselemental partitioningatom probe tomographyfirst-principles calculationsbccphase stabilitycomposition scanninglaser claddinghigh-entropy alloy coatingAZ91D magnesium alloywearkineticsdeformationthermal expansiondiamondcompositepowder metallurgyadditive manufacturinglow-activation high-entropy alloys (HEAs)high-temperature structural alloysmicrostructurescompressive propertiesheat-softening resistancetensile creep behaviormicrostructural evolutioncreep mechanismfirst-principles calculationmaximum entropyelastic propertymechanical propertyrecrystallizationlaser metal depositionelemental powdergraded materialrefractory high-entropy alloyselevated-temperature yield strengthsolid solution strengthening effectbulk metallic glasscomplex stress fieldshear bandflow serrationdeformation mechanismab initioconfiguration entropymatrix formulationcluster expansioncluster variation methodmonte carlothermodynamic integration(AlCrTiZrV)-Six-N filmsnanocomposite structurerefractory high entropy alloysmedium entropy alloys, mechanical propertiesthin filmsdeformation behaviorsnanocrystallinecoatinginterfacemechanical characterizationhigh pressurepolymorphic transitionsolidificationeutectic dendriteshierarchical nanotwinsprecipitation kineticsstrengthening mechanismselongation predictionweldingHall–Petch (H–P) effectlattice constantshigh-entropy ceramicsolid-state diffusionphase evolutionmechanical behaviorshigh-entropy filmlow-activation alloysResearch & information: generalZhang Yongedt464541Zhang YongothBOOK9910557430203321New Advances in High-Entropy Alloys3024610UNINA
