AlNAl纳米复合材料的制备、结构表征与性能研究的开题报告摘要本文介绍了AlN和Al纳米粒子构建的纳米复合材料的制备、结构表征和性能研究。首先文献综述了当前纳米复合材料的制备方法，在此基础上，采用机械合成法制备了AlNAl纳米复合材料。通过X射线衍射仪（XRD）、透射电子显微镜（TEM）等手段表征了样品的微观结构和化学组成，并进行了力学性能测试和热性能测试。结果表明，制备的样品具有高硬度和高热导率等优异的物理性能。该研究为AlN和Al材料的混合应用提供了参考价值，也对纳米复合材料的研究具有重要的意义。关键词：AlNAl；纳米复合材料；制备；表征；性能。AbstractThispaperintroducesthepreparation,structuralcharacterizationandperformanceresearchofAlNAlnano-compositematerialsconstructedbyAlNandAlnanoparticles.Firstly,thecurrentpreparationmethodsofnano-compositematerialsarereviewedintheliterature,andthenAlNAlnano-compositematerialsarepreparedbymechanicalsynthesis.ThemicrostructureandchemicalcompositionofthesamplewerecharacterizedbyX-raydiffraction(XRD),transmissionelectronmicroscopy(TEM)andothermethods,andmechanicalandthermalperformancetestswerecarriedout.Theresultsshowthatthepreparedsamplehasexcellentphysicalpropertiessuchashighhardnessandhighthermalconductivity.ThisstudyprovidesreferencevalueforthemixedapplicationofAlNandAlmaterials,andisofgreatsignificancefortheresearchofnano-compositematerials.Keywords:AlNAl;nano-compositematerials;preparation;characterization;performance.
