Title:MechanicalPerformanceTestingandSimulationAnalysisofCrAlBilayerNanoThinFilms
Abstract:
Nanomaterials,particularlythinfilms,havegainedimmenseattentioninvariousfieldsduetotheiruniquemechanicalproperties.Inthisstudy,weinvestigatethemechanicalperformanceofCrAlbilayernanothinfilmsusingacombinationofexperimentaltestingandsimulationanalysis.Theaimistogainabetterunderstandingofthemechanicalbehaviorofthesefilmsatthenanoscale.
Introduction:
CrAlbilayernanothinfilmshaveseveralpotentialapplications,includingprotectivecoatingsandelectronicdevices,duetotheirattractivecombinationofmechanical,electrical,andthermalproperties.However,acomprehensiveunderstandingoftheirmechanicalbehavioriscrucialfortheirsuccessfuluseinengineeringapplications.Inthisstudy,wefocusoncharacterizingthemechanicalpropertiesofCrAlbilayerfilmsatthenanoscale.
ExperimentalTesting:
ToevaluatethemechanicalpropertiesofCrAlbilayernanothinfilms,aseriesofexperimentswereconducted.Theseexperimentsincludednanoindentation,atomicforcemicroscopy(AFM),andtensiletesting.Nanoindentationwasperformedtodeterminethehardness,elasticmodulus,andfailurebehaviorofthefilms.AFManalysisprovidedavisualrepresentationoffilmtopographyandsurfaceroughness.Tensiletestingwasusedtoassessthefilm'sresistancetodeformationunderappliedstress,providinginsightsintothefilm'smechanicalstrengthandfracturebehavior.
