To increase pearlite, the cooling rate of the material needs to be decreased.

• Decrease the cooling rate of the material

• Increase the carbon content in the material

• Maintain a proper austenitizing temperature for the material

The strength of a material can be increased by factors such as alloying, heat treatment, and cold working.

• Alloying: Adding other elements to the base metal to improve its properties.

• Heat treatment: Heating and cooling the material to alter its microstructure and improve its strength.

• Cold working: Deforming the material at low temperatures to increase its strength.

• Grain refinement: Reducing the size of grains in the material to increase its strength.

• Controlled cooling: Cooling...read more
