1. Fine pearlite and a small amount of martensite are found in a quenched 1080 steel. What microstructure would be expected if we used a low-alloy, 0.2% C steel? What microstructure would be expected if we used a 4340 steel?
2. Explain the di¤erence between hardenability and hardness. Explain using a sketch how hardenability of steels is measured.
