Estimation of the effect of heat treatment of wire rope with different C and Mn content on values of new quality indicator W

Estimation of the effect of heat treatment of wire rope with different C and Mn content on values of new quality indicator W

$15.00

Instead of using three properties (Rm—tensile strength, Nb—number of bends, Nt—number of twists) for estimation of wire quality, this paper uses new indicators:
Wb = Rm/Nb; Wt = Rm/Nt; and W = Wb + Wt. It has been found that variations of properties Rm, Nb, Nt in wire drawn after patenting have exhibited higher values of the indicator W compared with wire drawn after normalizing. This study helps with selection of heat treatment methods for wire and wire rod containing different amounts of C and Mn based on calculation of the indicator W.
