Metallography and Microstructures of Cast Iron

Free graphite is a characteristic constituent of nonalloyed and low-alloyed cast irons. Precipi-tation of graphite directly from the liquid occurs when solidification takes place in the range be-tween the temperatures of stable transformation (T st) and metastable transformation (T mst), which are, respectively, 1153 C (2107 F) and 1147 C (2097 F), according to the iron-carbon diagram. In

Ultrasonic Testing of Ductile Iron Castings to Verify

Ductile iron is an iron-carbon casting material whose matrix includes carbon in the form of nodular graphite particles. Rounded graphite nodules in the ductile iron matrix offer greater resistance to stress concentration when compared to graphite flakes (as in gray cast iron) and, therefore, inhibit the creation of cracks. Safety-critical automotive components cast from ductile iron must be

PROPERTIES AND CHARACTERISTICS OF GRAPHITE

Thermodynamically, graphite at atmospheric pressure is the more stable form of carbon. Diamond is trans-formed to graphite above 1500C (Figure 1-4). The structure of graphite consists of a succession of layers parallel to the basal plane of hexagonally linked carbon atoms. The ideal graphite

Nondestructive characterization of flake graphite cast

The length of graphite is defined as the average diameter of the minimum circle circumscribing each graphite flake larger than 5 μm. The area fraction of graphite for CE4.7, CE4.1 and CE3.7 is 17.8, 12.6 and 10.0%, respectively. The length of the graphite flakes for CE4.7, CE4.1 and CE3.7 is 67, 39 and 28 μm, respectively. For details see .

Antisymmetric magnetoresistance in van der Waals

The FGT and few-layer graphite flakes were mechanically exfoliated onto SiO 2 /Si wafers in a glove box with oxygen and water levels below 0.1 parts per million. The nanoflakes were examined by optical microscopy. Atomically smooth flakes were identified with thicknesses of 5 to 20 nm for the top FGT, 40 to 80 nm for the bottom FGT, and 2 to 15 nm for the graphene. All three layers were

CORKWOOD GRAPHITE STUDIES
