摘要: We present a method whereby spatial variations in the resistivity of bulk conductive specimens may be detected on same scale as microstructural from which they arise. This technique, new development scanning tunneling potentiometry, offers significant benefits for characterization and investigation microstructure/resistivity relationships metallic materials.
