Steel, determination

It is agreed generally that the characteristics of the rust films that form on steels determine their resistance to atmospheric corrosion. The rust films that form on low-aUoy steels are more protec tive than those that form on unalloyed steel.

The chemical composition of the steel, determined by spectrographic analysis, is listed in Table 7.14. Based upon this composition, the steel is most likely SAE-AISI 1006 or 1010. The thickness of the steel averaged 1.84 mm.

The extent to which the corrosion of unalloyed steels is increased by contact with high-alloyed steels depends to a large extent on the surface area ratios. Figure 12 shows the corrosion rate of an unalloyed steel determined in natural seawater in contact with a high-alloyed stainless steel at various different area ratios.

If the ]3roducts of the Zr activity in the Bi with the activities of the X and C in the steel arc not sufficient to satisfy the respective equilibrium constants, the reactions will not occur, and the steel will not form ZrC or ZrX films. If the activity products are greater than the constants, A(ZrO or A(ZrN), the reactions will proceed until the activities are lowered to these alues. Thus, for a fixed Zr activity, the activities of N and C in the steel determine whether the carbide and nitride film-producing reactions should occur. The excess of X or C above these equilibrium values should be a measure of the driving force of reactions (21-1) and (21-2) to the right. 

The areas of application of quantiative X-ray powder diffraction are many and varied. Many hundreds of analysts are using this technique on a daily basis. Some of the more common applications would include ore and mineral analysis, quality control of rutile/anatase mixtures, retained austenite in steels, determination of phases in airborne particulates, various thin-film applications, study of catalysts, and analysis of cements. The current state of the art in the quantitative analysis of multiphase materials is that accuracies of the order of a percent or so can be obtained in those cases where the particle orientation effect either is nonexistent or has been adequately compensated for.
