Strength And Ductility

The deformation treatment of Fe360 low carbon steel by extrusion, equal-channel angular pressing, and equal-channel angular pressing with extrusion in one pass at a temperature of 673 K is considered.The strength increase in steel is shown for all methods of hardening. It is noted that in the range of temperature under consideration, the strength characteristics and the relative residual constriction of hardened steel samples are the parameters of low sensitivity to temperature decrease. The material destruction mechanism in various states under uniaxial tension under conditions of room and low temperature is analyzed.

Low Temperature Impact Toughness

The article deals with the fracture mechanism of thermomechanically processed low-carbon steel tested at low temperatures The low temperature impact toughness of the low-carbon Fe360 steel was defined in the initial (as delivered) state and after its combined treatment: quenching and equal channel angular pressing (ECAP) as well as quenching, equal channel angular pressing, and annealing. It was stated that the combination of quenching and the equal channel angular pressing provided higher strength and led to increased resistance to brittle fracture. Post-deformation annealing, due to high ductility of the material, allows for higher values of impact toughness and power intensity of fracture.
