| Abstract: | Three-point bend tests were conducted on the high cycle and high deformation fatigue crack growth rate of steel 16MnRE in aqueous H_2S saturated solution under different temperatures. Their corrosion fatigue activation energies were measured as 9.45 and 9.25 kcal/mol respectively. It may be proposed that the behaviour of corrosion fatigue cracking of steel 16MnRE in the saturated H_2S solution is mainly due to the hydrogen embrittlement and the rate of their crack growth is controlled by the hydrogen atom diffusion in steel. |
