Strengthening mechanism of cold drawing deformation of 1020 dual-phase steel wire

$15.00

High-strength rope wires were obtained by cold drawing 1020 dual- phase steel. TEM analysis showed that the martensite morphology, the dislocation densities of both martensite and ferrite phases as well as the morphology and amount of carbide particles are significantly affected by parameters of heat treatment and the degree of cold drawing. A suitable combination of the technological parameters of heat treatment and cold drawing c
