Experimental Analysis on Martensite Formation of Low Carbon Steel During Rapid Cooling Process

Rapid cooling is one of the heat treatment techniques, which has been adopted in manufacturing sheet metal forming products such as structural beam and automotive parts. It involves heating of the carbon steel, and then followed by fast cooling process inside the cooling medium such as water and oil...
