Fig. 32 SEM micrograph of a longitudinal section at a quenched interface showing two pearlite colonies (A and B) growing into austenite in a Fe-0.8C alloy. Electropolished surface prepared for SACP analysis. Original magnification, 1700× More

Fig. 919 Longitudinal section through a tension fracture in a warp wire of a Fourdrinier wire cloth of phosphor bronze C. Slip lines are visible throughout the microstructure. Plastic flow and reduction in area at the fracture (top) were attributed to excessive warp tension, FeCl 3 etch, 265× More

Fig. 920 Longitudinal section through a fatigue fracture in a shute (weft) wire of Fourdrinier wire cloth of 80Cu-20Zn brass with 0.5% Sn added. The profile of the fracture is shown at top. Note corrosion pitting visible on the wire surface at left and at right, FeCl 3 . 265× More

Fig. 528 Longitudinal section through a spline of the shaft in Fig. 525 , showing inclusions, banding, and some free ferrite. The cause of the fracture was improper design; corners at bases of splines had adequate radii for most of the spline length, but these radii were reduced, forming More

Fig. 529 Longitudinal section through the same spline as in Fig. 528 , displaying the size and even distribution of the inclusions in the steel. Some of the inclusions were found to be as long as 8 mm ( 5 16 in.). Etched in 1 part HCl, 1 part H 2 O. 2× More

Fig. 8 Two broken Moore pins from cobalt-chromium alloy. (a) Longitudinal section through fracture surface showing grain-boundary precipitates and a partially intercrystalline fracture. 63×. (b) SEM fractograph indicating grain-boundary separation. Compare with (e). (c) Longitudinal section More

Fig. 3 Longitudinal section through a hot-rolled 1041 steel bar showing a carbon-rich centerline (dark horizontal bands) that resulted from segregation in the ingot. Picral. 3×. Courtesy of J.R. Kilpatrick More

Fig. 10 Longitudinal section through an ingot showing extensive centerline shrinkage More

Fig. 11 1038 steel bar, as-forged. Longitudinal section displays secondary pipe (black areas) that was carried along from the original bar stock into the forged piece. Gray areas are pearlite; white areas, ferrite. 2% nital. 50× More

Fig. 11 Longitudinal section through a metal fin that was formed by a bleedout on the surface of an ESR nickel superalloy ingot. Note: The circular, dark-etching features are nickel balls introduced in an experiment to delineate the shape of the molten pool. They are not related More

Fig. 4 4047 steel forging (longitudinal section: 16 mm, or 0.625 in., thick) austenitized at 830 °C (1525 °F), cooled to 665 °C (1225 °F) and held 6 h, furnace cooled to 540 °C (1000 °F), then air cooled. Ferrite (white) and lamellar pearlite (dark). 2% nital etch. Original magnification: 500× More
