Effect of Processing Parameters on the Mechanical

A good yield,tensile strength,and fracture toughness are expected in the microstructure presenting 100% of ferrite due to the presence of silicon and manganese.Both elements harden and strengthen the ferrite and accordingly increase the yield and tensile strength .
