摘要: 为了研究2205双相不锈钢/16MnR 爆炸复合板界面的微观结构,用金相显微镜和扫描电镜 (SEM)观察了复合界面的形貌;用显微硬度计测定了爆炸复合界面的显微硬度;分析了热处理对显微硬度的 影响。研究表明:基材和复材的显微硬度随着退火加热温度的提高和保温时间的延长而降低;2205双相不锈 钢在850℃加热保温8h后炉冷到400℃出炉空冷会析出相。Abstract: Theexperimentalsamplewiththedimensionsof25mm50mmwasformedwitha4-mmthickness2205duplexstainlesssteel( DSS)plateastheflyerbaseanda20-mm-thichness16MnRsteel plateasthebaseplatebyexplosivecombination.Theflyerplateandbaseplateweretreatedwithdifferentmethods, respectively.ThebondinginterfacemorphologywasobservedwithaNikonEpiphot 200inverted microscopeanda HitachiS-3000Nscanningelectron microscope (SEM).Thewhole bondinginterfaceismadeofstraightandvorticalbondzonesandcanbedividedintomeltandplastic deformationzones.AndEnergydispersivespectroscopyanalysisdisplaysthatthebondinginterface takesonasatisfactorymetallurgicalbond.TheexperimentalsampleswereannealedinanelectricresistancefurnaceSX- 4-10andthemicrohardnesswasmeasuredbyanHV-1000cleraometer.Afterthe samplewasheat-treatedat850℃for8handcooleduntil400℃,andcooledinair,inthe2205DSS platetherewas-phaseprecipitatedintheaustenite-ferriteinterspaceorinferrite.Andafterthesamplewasheat- treatedat700℃for8handcooleduntil400℃,andcooledinair,therewasnot-phase observedinthebondinginterface.Analysisofheattreatmentinfluencesonthemicrohardnessindicatesthatthemicrohardnessofthebaseandflyerplatesdecreaseswiththeincreas ngoftemperature andtimeofheattreatment.
