white cast iron microstructure

The chemical composition of the cast iron is Fe-3.52C-2.51Si-0.49Mn-0.15Mo-0.31Cu wt%. All samples are etched using 2% nital. Colour micrographs are produced by 

Like gray cast iron, white cast iron features many small fractures. The difference is that white cast iron features cementite below its surface, 

As seen in Fig: 2, the microstructure of white cast iron is completely different from gray cast iron. In this microstructure, there are no graphite flakes present. The bigger, dark gray, rounded

In grey irons, the carbon is present as graphite; in white cast iron it is present in the form of iron carbide and alloy carbides. Cast iron has good 

chromium cast iron. They found that tungsten can effectively improve the hardness of the matrix and wear resistance of the high chromium cast iron. CHUNG, et al[3], investigated the effect of alloying titanium addition on the microstructure and wear resistance of hypereutectic high chromium white cast iron. The results showed that a fine

3.The realization mechanism of as-cast microstructure (1) to determine the proper carbon content, one can ensure that 20% ~ 40% alloy carbides are obtained while leaving high carbon austenite, and the other can make alloy carbides of a single M 7 C 3 type with the proper amount of chromium.

1 shows the microstructure of high Cr alloyed white cast iron in the as-cast state. The matrix structures can be pearlite, austenite, and martensite or some 

white cast iron microstructure (Fig. 4) does not contain free graphite as does gray iron, malleable iron, or ductile iron. The fracture surface of this alloy appears white. In Fig. 4 the dark

21/03/  · This microstructure is of white cast iron with 3-3.5 wt% C. In this microstructure, we clearly see two phases appearing in the microstructure. While you perform etching of material,

A white cast iron with nano-eutectic microstructure was prepared by an aluminothermic reaction casting. Microstructures of the cast iron were investigated by optical microscope (OM), electron probe micro-analyzer (EPMA), scanning electron microscope (SEM) and X-ray diffraction (XRD). Mechanical properties of the cast iron were tested.

White cast iron displays white fractured surface due to the presence of cementite. With a lower silicon content (graphitizing agent) and faster cooling rate
