Hydrogen embrittlement of cold drawn prestressing steels: the role of the die inlet angle
Cold-drawn prestressing steel wires are susceptible to hydrogen embrittlement (HE) in aggressive environments, and residual stress-strain states generated in wires by the drawing process play the key role there. Correspondingly, alterations of the stress-strain fields due to peculiarities of the...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Summary: | Cold-drawn prestressing steel wires are susceptible to hydrogen embrittlement (HE) in aggressive
environments, and residual stress-strain states generated in wires by the drawing
process play the key role there. Correspondingly, alterations of the stress-strain fields due
to peculiarities of the drawing procedure affect the serviceability of wires under HE. On
the basis of performed numerical simulations of the process of cold drawing with the use
of different drawing dies, the paper addresses the effect of the inlet angle of the die on residual
stress-strain fields in wires, and derives their consequences for wires hydrogenation
and their susceptibility to HE. The reduction of the die inlet angle is shown to be beneficial
for the wires performance. |
