Abstract: Effects of dual phase treatment on microstructure and mechanical properties of S135
drill pipe steel were studied by means of optical microscope (OM), scanning electron microscopy
(SEM) and mechanical property testing. The results show that the ferrite-martensite dual phase
microstructure is obtained for the steel heat-treated at the temperatures of 760-800°C. With
increasing of dual-phase treatment temperature, the volume of martensite increases and the
volume of ferrite decreases, the strength and hardness of the steel increase, the plasticity and
toughness of the steel decrease, the fracture mode changes from ductile fracture to brittle
fracture. The work-hardening exponent of the steel increases, and two n values are observed for
the steel after dual-phase treatment.
