The increase in Si and V contents led to significant modifications in the microstructures, being perlite the main phase, with the presence of 

The microstructures consisted of M 7 C 3 and M 23 C 6 primary carbides as well as eutectic and secondary carbides. The M 23 C 6 was stated to have transformed from primary M 7 C 3 during the destabilisation treatment. Their BSE images showed that NbC to be located inside and on the edge of primary Cr-carbides.

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

The microstructure of cast iron ABSTRACT White cast iron produces more cementite than graphite during solidification, it is a hard brittle alloy containing massive amount of fe3c. Alloyed white cast iron is used due to their hardness and wear resistance for abrasive wear. The name was given due to white fractured surface.

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.

Most white cast irons contain less than 4.3% carbon, with low silicon contents to inhibit the precipitation Ferritic Malleable Cast Iron Microstructure.

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

Whiteheart malleable cast iron - It is a decarburized cast iron. The microstructure of whiteheart malleable cast iron depends on section size. Small sections contain pearlite and temper carbon in ferritic substrate.

Cast irons typically contain 2-4 wt% of carbon with a high silicon concentrations and a greater concentration of impurities than steels. The carbon equivalent (CE) of a cast iron helps to distinguish the grey irons which cool into a microstructure containing graphite and and the white irons where the carbon is present mainly as cementite.

Microstructures of Cast Iron Janina M. Radzikowska, The Foundry Research Institute, Krako´w, Poland CAST IRON is an iron-carbon cast alloy with other elements that is made by remelting pig iron, scrap, and other additions. For differentia-tion from steel and cast steel, cast iron is defined as a cast alloy with a carbon content (min2.03%)

Cast iron is an iron-carbon-silicon alloy used in numerous industrial applications, such as the base structures of manufacturing machines, rollers, valves, pump bodies and mechanical gears, among others. The main families of cast irons are: nodular cast iron, malleable cast iron, grey cast iron and white cast iron (Callister, 2006). Their
