Abstract

Fatigue crack propagation (FCP) tests were performed in NaCl solution under controlled cathodic potentials to achieve the hydrogen charged condition where anodic dissolution does not occur so much to understand the effect of hydrogen on FCP behavior of wrought magnesium alloy AZ61. FCP rates were accelerated under the hydrogen charged conditions compared with dry air. A grazing incidence X-ray diffraction (GIXRD) and a thermal desorption spectrometry (TDS) analysis revealed that FCP rates have no relation to hydrogen compounds formed near the crack surface. This indicates the acceleration could be mainly attributed to hydrogen diffusion and hydrogen embrittlement is dominant in the FCP behavior of AZ61.
