Effects of Plastic Deformation, Heat Treatment and Molybdenum and Nickel Concentration on Lath Martensitic Microstructure

Article Preview

Abstract:

Lath martensitic microstructures were produced in steels containing 0.15% of carbon and various amounts of molybdenum and nickel. The behavior of the lath martensitic microstructure was studied during cold rolling in steels with six different chemical compositions. All materials have endured 75% deformation without damage. In addition, the effects of heat treatments on microstructures and hardness were investigated as well.
