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

Microstructure White Cast Iron It is difficult to cool thick castings fast enough to solidify the melt as white cast iron all the way through. However, rapid 

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:- White Cast Iron Microstructure. The typical microstructure of white cast iron, consisting of dendrites of transformed austenite. (pearlite) in a white 

The as-cast microstructure of Fe-Cr-C-V white irons consists of M7C3 and vanadium rich M6C5 carbides in austenitic matrix.

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

01/08/  · Eeffect of Boron addition on the microstructure and mechanical properties of ductile iron, GJS-500-7 grade was studied. Three cast batches with the Boron content of 10, 49 and 131ppm were cast in

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.

The term cast iron refers to iron-carbon-silicon alloys that contain 2.5-4 % carbon and usually 1-3 % silicon. 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 castability and machinability, as well as moderate mechanical properties.
