Introduction:
Aluminumalloyspossessexcellentmechanicalproperties,suchashighstrength-to-weightratio,goodcorrosionresistance,andexcellentformability,makingthemanattractivechoiceforvariousindustrialapplications.Amongthedifferentaluminumalloycompositions,3004isawidelyusedalloyduetoitsexceptionalcombinationofstrength,formability,andweldability.Thepropertiesof3004aluminumalloycanbefurtherenhancedthroughannealing,aheattreatmentprocessthatinvolvesheatingthematerialtoaspecifictemperatureandthencoolingitslowly.Annealinginfluencesthemicrostructureandmechanicalpropertiesofthealloy,allowingforimprovedperformanceindifferentapplications.
ExperimentalMethodology:
Theexperimentalstudywascarriedoutusing3004aluminumalloysamples,whichunderwentannealingtreatmentatdifferenttemperaturesandtimedurations.Toexaminethemicrostructure,metallographicanalysiswasperformedusinganopticalmicroscope.ThehardnessoftheannealedsampleswasmeasuredusingaVickershardnesstester.Tensiletestswereconductedtoevaluatethemechanicalstrengthandductilityofthealloy.Thetestresultswerecomparedwiththoseofthenon-annealedalloytodeterminetheeffectsofannealingonthealloy'sthermal-mechanicalbehavior.
ResultsandDiscussion:
Themicrostructuralanalysisrevealedsignificantchangesinthegrainstructureof3004aluminumalloyafterannealing,withtheformationoflargerandequiaxedgrains.Thisresultindicatedgraincoarseningduetorecrystallizationduringtheannealingprocess.Thehardnessoftheanneale
