Abstract EN
The 1045 steel with lamellar spacing of pearlite in nanometer was prepared by aluminothermic reaction casting and annealed at 873 K (600°C) with different time.
Microstructures of steels were investigated by X-ray diffraction (XRD), scanning electron microscope (SEM), and transmission electron microscope (TEM).
Tensile properties of the steels were measured.
The results showed that the lamellar spacing of the pearlite increased with the annealing time.
It was found that the microstructure of steels consisted of nanocrystalline-ferrite matrix and laminar pearlite phase.
The average grain sizes of the ferrite were 26.9, 27.0, 26.1, and 34.9 nm for the cast steel and samples annealed for 2, 4, and 6 h, respectively.
As the annealing time increased, the volume fraction of the pearlite almost remained constant, while the laminar spacing of pearlite increased from 146 to 300 nm.
The tensile and yield strength varied slightly; the elongation obviously improved.
After annealing for 4 h, the elongation increased to be 33%, which was the reported highest value for the steel up to now and about twice of the conventional 1045 steel.
