摘要：
The influence of shot peening on the fatigue properties of duplex stainless steel reinforcing bars manufactured using both hot and cold rolled processes was studied. From determination of the S-N curves, the experimental results show that shot peening improves the fatigue behaviour of the re-bars, but that the improvement is much greater for the hot rolled bars. A more severe peening action capable of promoting greater plastic deformation of the bar surface needs to be used to improve the fatigue resistance of cold rolled corrugated bars.
