泡沫铝形态结构特征分析的数字图像技术及方法

In this paper, from perspective of digital-image, the related imaging technology and analysis method applied to surveying to aluminum foams’ microstructure characteristics are discussed. The study first introduces the main parameters of microstructure feature briefly, then discusses the existed two levels that 2D analysis based on 2D transection and 3D analysis based on volume data. From the view of 2D level, paper mainly talks about quantitative analysis on Metallographic cross, then centers on the XCT technique and exsiting research state applied to the 3D characterization of cellular materials. At the end of this paper some conclusions are made to these different researching methods. The work of this study investigates the general situation on the associated methods of digital-image, which gives researchers a guide to the study of aluminum foam.
