ResearchonthePulsedLaserInducedBehaviorof55%SiC_pAlCompositeMaterials
Abstract:
Compositematerials,especiallythosereinforcedwithsiliconcarbide(SiC)particles,havegainedsignificantattentioninrecentyearsduetotheirexceptionalmechanicalandthermalproperties.Inthisstudy,thebehaviorof55%SiC_pAlcompositematerialsunderpulsedlaserirradiationwasinvestigated.Theeffectsoflaserenergy,pulseduration,andpulsefrequencyonthematerial'sresponsewereexamined.Theresultsindicatethatthelaser-inducedbehaviorofSiC_pAlcompositesisdependentontheseparameters.Understandingtheresponseofthesematerialsunderlaserirradiationiscrucialfortheirpotentialapplicationsinvariousfields.
Introduction:
SiCparticleshavebeenwidelyusedasreinforcementinmetalmatrixcompositesduetotheirhighstrength,goodthermalconductivity,andlowdensity.TheincorporationofSiCparticlesinaluminum(Al)matriceshasshownpromiseinimprovingthematerial'smechanicalandthermalproperties.However,thebehaviorofSiC_pAlcompositesundertheinfluenceofanexternalenergysource,suchaspulsedlaserirradiation,hasnotbeenextensivelystudied.Thus,itisimportanttoinvestigatethelaser-inducedbehaviorofthesecompositesandestablishafoundationfortheirfutureapplications.
ExperimentalMethodology:
TheSiC_pAlcompositeswerepreparedusingpowdermetallurgytechniques.Laserirradiationexperimentswereconductedusingapulsedlasersystem.Thelaserenergy,pulseduration,andpulsefrequencywerevariedtounderstandtheireffectsonthematerial'sresponse.Thetemperaturedistributionandthermalstressinthematerialweremeasuredusingthermalimagingandstraingaugetechniques,respectively.Themicrostructuralchangesbeforeandafterlaserirradiationwereexaminedusingscanningelectronmicroscopy(SEM).
ResultsandDiscussion:
ThelaserirradiationexperimentsontheSiC_pAlcompositesshowedthatthelaser-inducedbehaviorisinfluencedbythelaserenergy,pulseduration,andpulsefrequency.Atlowerlaserenergylevels,thetemperaturedistributioninthematerialremainsrelativelyuniform,withlimitedmicrostructuralchangesobserved.Asthelase
