Microstructure of Various Cast Irons and Quantification
1. Vermicular graphite is a characteristic of
2. Eutectic reaction in the Fe-Fe3C phase diagram occurs at
3. Heavy machinery bases are made of
4. The purest form of iron
5. Higher corrosion resistance can be obtained from cast iron due to which alloying addition.
6. Assertion: Poor machinability of grey cast iron is due to the presence of graphite flakesReason: Graphite flakes have good damping capacity and act as a chip breaker to lubricate tools and machines.
