Mechanical properties and structural evolution during Warm Forging of Carbon Steel

  Ashutosh Kumar,  Ajit Kumar,  Rohit Kumar

Warm forging is the plastic deformation of a metal at temperatures below the recrystallization temperature range and above room temperature; typically in the temperature range of 600-900ºC. Warm working combines the advantages of both cold and hot working. Compared to cold/hot forging, warm forging offers the advantages of fewer forming steps as a result of greater workability, reduced loads, energy savings, high material utilization. This work has done on En 24 and 1018 low carbon steel to establish quantitative knowledge of mechanical properties occurring during the warm working at the temperature of 800°C with the help of different processing parameters (amount of deformation, soaking time and strain rate). The paper shows that the hardness, toughness and strength increases with increase in deformation after warm forging. It also affects the toughness value. Microstructure along with volume percentage of retained austenite also estimated to get proper explanation for high or low toughness. Finally optimum forging and parameters are used to impart the benefits of warm forging than cold or hot forging for carbon steel.

Keywords- Warm Forging, Hardness, Toughness, Strength, Low Carbon Steel.
