【摘要】 Zr-4合金在高压釜中经360℃高温水腐蚀后,用扫描探针显微镜(SPM)研究了氧化膜中的显微组织和晶粒形貌。由于SPM具有很高的水平和垂直分辨率,适合于观察表面只有微小起伏的显微组织,所以能够清晰地观察到氧化膜中的裂纹、空洞和晶粒等显微组织。测试样品的制备方法简便。更多还原

【Abstract】 The microstructure of oxide films formed on zircaloy-4 tested in autoclave at 360 ℃ ,18. 6 MPa is investigated by means of scanning probe microscopy (SPM). The microstructure with only slight undulation on the surface can be examined by SPM,because it has very high resolution both on horizontal and vertical directions. So that the microstructure of cracks, pores and grains in oxide films can be clearly observed. The method for the preparation of SPM specimens is simple and convenient.更多还原
