K.B. Rundman, in Encyclopedia of Materials: Science and Technology, 2001 14 Malleable Cast Iron, Processing, Microstructure, and Mechanical Properties. Malleable cast iron has lower CE (Table 1) than gray cast iron, solidifying white.The phase diagram and the cooling curve characteristic of white cast iron are illustrated in Fig. 1.It can be seen in the cooling curve that

06/07/  · Depending on the carbon content, white cast iron can be divided into eutectic cast iron (4.3 % C), hypoeutectic cast iron (<4.3 % C) and hypereutectic cast iron (>4.3 % C). The microstructure formation and transformation during solidification and cooling of such types of cast iron are explained in more detail below. Eutectic cast iron

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

The microstructure of the high boron white cast iron comprises a dendritic matrix and interdendritic eutectic boride M 2 B in as-cast condition, where M represents Cr, Fe, or Mn. The boride morphology is much like that of carbide in high chromium white cast iron, but its microhardness is higher than carbide.

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

Therefore, in this part will discuss on white cast iron and its microstructure. Then, it is followed by mechanical properties and sand casting process. 2.2 METAL CASTING PROCESS Casting is a 6000 year young process which is mentioned in several Sanskrit works

Fig. Microstructure For Cast Iron. 1) Gray cast iron: These alloys consists carbon in form graphite flakes, which are surrounded by either ferrite or pearlite. Because of presence of graphite, fractured surface of these alloys look grayish, and so is the name for them. White cast iron: When Si content is low (less than 1%) in combination

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

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

Therefore, in this part will discuss on white cast iron and its microstructure. Then, it is followed by mechanical properties and sand casting process. 2.2 METAL CASTING PROCESS Casting is a
