... and conducted fatigue tests of steel wires. The results showed that the stress concentration of triangular pits was more obvious than that of circular pits, and the fatigue strength reduced more seriously. Therefore, the severity of pit corrosion was much higher than other corrosion types for steel wire (Cao...
