Content effect on intergranular

Fig. 7.57 Effect of carbon and nickel content on intergranular corrosion penetration rate of 1 8 wt% Cr-base stainless steels. Alloys sensitized for 100 h at 550 °C. Immersion in boiling 65% nitric acid. Pds., periods (48 h) of exposure. Redrawn from Ref 84...

Silt content affects the c values through its influence on m and hydraulic conductivity k. For the same sand-silt mix at different proportions of silt content, m appears to be influenced by equivalent intergranular void ratios (Figure 6a-b). Hydraulic conductivity is affected by both void ratio and silt content. Silt content has a significant effect on k than the influence of void ratio on k. Hydraulic conductivity of the soil specimens in this study ranged from 0.6 to 1.3x10 cm/s for the clean sand, 9x10 cm/s for 15% silt content. 

The effect of matrix concentration on orientation, intergranular interactions and magnetic properties has been investigated for /,10 FePtiAg nanocomposite films. The Ag contents varied from 0 to 20 vol %. As shown in Fig. 33, all films clearly show the (001) superlattice peaks indicating that the Ag content (matrix) has relatively small affection on orientation. 

Effect of Thermal History of Austenitic Stainless Steels on Susceptibility to Intergranular Corrosion. The time dependence for the local depletion of chromium sufficient to cause susceptibility to intergranular corrosion as functions of temperature and carbon content is of the form represented in Fig. 7.54 (Ref 83). The curves are typical of type 3xx alloys with nominal chromium concentrations of 17 to 25 wt% and, since they represent times for initiation of intergranular corrosion,...
