Digital Library of Periodicals of National Academy of Sciences of Ukraine| Резюме: | Changes in the plasticity characteristics in air and in a hydrogenating environment of
prestressing steel wires due to cold drawing process are investigated on the basis of slow
strain rate tests on smooth specimens. The tested pearlitic steel is highly susceptible to
hydrogen embrittlement at all stages of cold drawing. The inconsistency is revealed
between the changes of two plasticity characteristics: reduction in area and uniform elongation.
The obtained results are analysed distinguishing the contribution of resistance to
crack initiation and crack propagation. Susceptibility to crack initiation increases as a
result of cold drawing with simultaneous improvement of the crack propagation resistance. |
