Ultrafine-grained low carbon steels by severe plastic deformation (SPD)
The structure and properties of 0, 14% C and 0, 1% C - B low-carbon steels taken in two initial states, martensitic and ferritic-pearlitic, were studied after cold equal-channel angular (ECA) pressing. ECA pressing leads to the formation of only partially submicrocrystalline structure with a grain size of 150 – 300 nm, depending on the steel alloying and initial state. The finest structure with the elements of 190 nm in size is obtained in the 0, 1% C - B steel microalloyed with boron. The strength of the 0, 1% C - B steel after cold ECA pressing (Rm = 805-1235 MPa) meets the specifications of fasteners of the R80 - R120 strength grade. The strength of the deformed 0, 14% C steel is close to the R80 strength grade.
