“…It opens up new possibilities for detailed investigation of the LME crack initiation mechanism because this is a perfectly suited size for applying surface analysis techniques such as Auger/XPS spectroscopy. Indeed, it has become customary for the last 30 years in corrosion science to study the oxide structure and evolution by Auger/XPS techniques [3,4]. Working under ultra high vacuum (UHV) also allows preparing surfaces with specific oxidation states.…”

Auger electron spectroscopy has been applied to the quantitative surface analysis of a series of metals (Ag, Cd, In, Sn), Indium-tin alloys, Indium and tin oxides, and Indlum-tln oxide (ITO) films. Spectra were obtained by two methods: (1)the conventional modulation technique, which results In the derivative spectrum, and (2) a direct current measurement, which gives an undifferentiated spectrum. For data collected In the latter mode, an Instrumental approach and secondary electron background correction are discussed. Quantitative results obtained by using this approach are shown to be more accurate than the traditional measurement method.

“…The "multilayer segregation" approach includes information about the composition below the surface. This information can be represented either by the Auger peak heights (APH) of individual elements measured after removal of the top atomic layer [52,53] (equation (5a) and (5b) in Table 1) or by the derivative of the APH depth profiles at the surface [54] (equation (6) in Table 1). Evidently, the methods of "multilayer segregation" can be also applied to both to the case of homogeneous distribution of elements in the …”

Roles of molybdenum, silicon or aluminum in ferritc on grain boundary segregation and hence on intergranular fracture have been investigated by using Auger electron spectroscopy (AES) and tensile test. Competitive segregation between sulfur and carbon or nitrogen, which caused the decrease below 7(10"C of sulfur content at the grain boundaries, was observed in the pure iron. The intergranular brittleness of the pure iron was caused by sulfur at the grain boundaries. When molybdenum was added to the pure iron, the sulfur contents at the grain boundaries were lowered in comparison to those in the pure iron. The molybdenum-bearing alloy showed higher fracture strength than that of the pure iron, and fractured mostly in the transgranular mode. This arises from the intrinsic effect of molybdenum on the grain boundaries as well as the decrease in sulfur content. In the 3.37 wt.%Si alloy, silicon and carbon or nitrogen competitively segregated to the grain boundaries, and such a compe:itive segregation was also observed between sulfur and carbon or nitrogen. The sulfur content at the grain boundaries decreased with increasing silicon content. The fracture modes in the 3.37-and 4.26 wt.%Si alloys were transgranular in the rolling direction, but were mostly intergranular in the transverse direction and in the as-rolled condition. The intergranular characteristic in the fracture behavior may be attributed to the detrimental effect of silicon as well as sulfur on the intergranular cohesion. Carbon and aluminum only were found at the grain boundaries of the aluminumbearing alloy. This suggests that aluminum is a strong repulser of sulfur or nitrogen at the grain boundaries. Additionally, it was found that aluminum has a detrimental effect on grain boundary strength of ferrite.
