Title:ApplicationofDOE(DesignofExperiments)inEnhancingtheImpactToughnessof30CrNiMoSteelQuenchedandTemperedBars
Abstract:
ThispaperfocusesontheapplicationofDesignofExperiments(DOE)inimprovingtheimpacttoughnessof30CrNiMosteelquenchedandtemperedbars.The30CrNiMosteeliswidelyusedinvariousindustriesduetoitsexcellentmechanicalproperties,butitsimpacttoughnesscanbefurtherimprovedusingexperimentaldesigntechniques.Inthisstudy,wewilldesignandanalyzeaseriesofexperimentstooptimizetheimpacttoughnessof30CrNiMosteelthroughDOEtechniques.Theresultswillprovidevaluableinsightsforenhancingthemechanicalpropertiesofthissteelgrade.
