This study aims to investigate tensile properties and work hardening behavior of dual phase(DP) steels. A series of DP steels containing ferrite and martensite with different volume
fractions of martensite (Vm) were produced by intercritical heat treatment. Microstructural
investigations, hardness test, and tensile test were carried out. The experimental results showed
that dual phase steels at 760
o
c and 10s have excellent mechanical properties in terms of tensile
strength, ductility and fracture energy. A further increase in Vm was found to increase tensile
strengths and ductility. The increasing and then decreasing trend in tensile strength is in contrast
to the law of mixture. These unusual behaviors are discussed and explained. Work hardening
behavior was analyzed in terms of Holloman analysis
