Fig. 4.16 Sulfur print of a steel rail showing regions of sulfur segregation. 1× More

Fig. 3 The sulfur cycle showing the role of bacteria in oxidizing elemental sulfur to sulfate ( SO 4 2 − ) and in reducing sulfate to sulfide (S 2– ). Source: Ref 12 More

Figure 1-38 Mirror-image sulfur print of the macroetched disc shown in Fig. 1-6 . More

Figure 1-39 Sulfur print intensity is influenced by the composition of the sulfide inclusions. Both of the sulfur-printed discs shown contain 0.06% sulfur, but the print on the left is very light because most of the sulfides contain considerable chromium and are low in manganese content More

Figure 6-21 Inclusion volume fractions of nine samples of varying sulfur contents evaluated by the manual point-counting method (100 fields with a 100-point test grid at 500 × for each sample). (From Vander Voort, Ref. 61, courtesy of Plenum Press.) More

Figure 6-22 Inclusion volume fractions of nine samples of varying sulfur contents evaluated by the lineal analysis technique using a Hurlbut counter (1000 ×). (From Vander Voort, Ref. 61, courtesy of Plenum Press.) More

Figure 6-23 Inclusion volume fraction measurements of nine samples with varying sulfur contents using image analysis with 16×, 32×, and 80 × objectives. The trend line shown was plotted by using the least-squares method to fit all the data points. (From Vander Voort, Ref. 61, courtesy More

Fig. 3 Optimum range of initial sulfur level as a function of type (figure) and amount (table) of minor elements used for graphite compaction. The table shows the sulfur range, Δ S , for compacted iron formation with different spheroidizers in an iron composition of 3.5% C, 2.1% Si, 0.75% Mn More

Fig. 12 Effect of sulfur content on transverse impact energy at room temperature in a silicon-aluminum killed steel More

Fig. 15.37 Sulfur prints of transverse cross sections of rails. Modern rail steels have chemical compositions and sulfur levels that give little information in sulfur prints. Print (a) corresponds to the macrograph of Fig. 15.36(b) . Print (b) corresponds to the macrograph of Fig. 15.36(c More

Fig. 17.59 The effect of the difference between the actual sulfur content of a gray cast iron and that needed to cause the precipitation of MnS at the liquidus temperature of the alloy. T ℓ is the liquidus temperature. All experiments performed with S = 0.12% and C eq = 3.8% with different More

Fig. 5.42 Effect of sulfur on the carburization kinetics of Ni-30Cr alloy. Vertical axis is mass gain per unit area, and horizontal axis is exposure time in hour. The test began with oxidation at 1000 °C (1832 °F) in a CO-CO 2 environment for about 40 h, and then switched to carburization More
