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: generalbicssc(AlCrTiZrV)-Six-N films(CoCrFeNi)100−xMox alloysab initioadditive manufacturingalloy designalloys designannealingannealing treatmentatom probe tomographyatomic-scale unstableAZ91D magnesium alloybccbulk metallic glassCALPHADCCACCAscluster expansioncluster variation methodcoatingcoherent microstructurecomplex concentrated alloyscomplex stress fieldcompositecomposition scanningcompositionally complex alloycompositionally complex alloyscompressive propertiesconfiguration entropyconventional alloyscorrosioncorrosion behaviorcreep mechanismCrFeCoNi(Nb,Mo)Curie temperaturedeformationdeformation and fracturedeformation behaviorsdeformation mechanismdensity functional theorydiamonddifferential scanning calorimetry (DSC)elastic propertyelectron microscopyelemental additionelemental partitioningelemental powderelevated-temperature yield strengthelongation predictionentropyeutectic dendritesfirst-principles calculationfirst-principles calculationsflow serrationgamma double prime nanoparticlesgraded materialgrain refinementHall-Petch (H-P) effecthardening behaviorhardnessHEAHEAsheat-softening resistancehierarchical nanotwinshigh entropy alloyhigh entropy alloyshigh pressurehigh-entropy alloyhigh-entropy alloy coatinghigh-entropy alloyshigh-entropy alloys (HEAs)high-entropy ceramichigh-entropy filmhigh-entropy filmshigh-pressure torsionhigh-temperature structural alloysimmiscible alloysin situ X-ray diffractioninterfaceinterstitial phaseion irradiationkineticslaser claddinglaser metal depositionlattice constantslattice distortionlightweight alloysliquid phase separationlow-activation alloyslow-activation high-entropy alloys (HEAs)magnetic propertiesmagnetic propertymatrix formulationmaximum entropymechanical alloyingmechanical behaviorsmechanical characterizationmechanical propertiesmechanical propertymedium entropy alloymedium entropy alloys, mechanical propertiesmetal matrix compositesmicrohardnessmicrostructural evolutionmicrostructuremicrostructuresmiscibility gapsmonte carloMPEAsmulti-principal element alloysmulticomponentmulticomponent alloysnanocomposite structurenanocrystallinenanocrystalline materialsnanodisturbancesnanoprecipitatesnanoscaled high-entropy alloyspartial recrystallizationphase compositionphase constituentphase constitutionphase evolutionphase stabilityphase structuresphase transformationphase transformationsphase transitionplasticityplasticity methodspolymorphic transitionpowder metallurgyprecipitationprecipitation kineticsrecrystallizationrefractory high entropy alloysrefractory high-entropy alloysscandium effectserration behaviorshear bandsodium chloridesolid solution strengthening effectsolid-solutionsolid-solution alloyssolid-state diffusionsolidificationspark plasma sinteringspecific heatsputteringstacking-fault energystrain rate sensitivitystrengtheningstrengthening mechanismsstructural metalssulfuric acidtensile creep behaviortensile strengththermal expansionthermodynamic integrationthermoelectric propertiesthin filmstransmission electron microscopyvolume swellingwearwear behaviourweldingResearch & information: generalZhang Yongedt464541Zhang YongothBOOK9910557430203321New Advances in High-Entropy Alloys3024610UNINA
