摘　　要：透射电镜(TEM)分析技术是揭示材料宏观性能与其显微结构之间的内在关联性的重要手段,但样品制备难度较高。通过实践过程选择了一种用于萃取复型样品制备过程的化学溶解脱膜法,该方法的应用使萃取复型法过程易于操作,并确保了其成功率。同时,针对样品制备过程中的各个关键步骤和环节,提出了低合金高强钢萃取复型样品制备的关键技术要点。TEM analysis technique plays an important role in revealing the relationship between the macroscopic properties and the micro-structure of materials, but its samples preparation is difficult. A chemical dissolving technique of peeling off carbon-film for the extraction replica of TEM sample preparation was put forward, wish the advantage of easy operation. The extraction replica key techniques for TEM sample preparation of low alloying high strength steels were introduced in detail.
