| Abstract | The effect of electrochemical hydrogen charging on the mechanical properties and fracture behavior of a dual-phase Ti-4Al-2V-1Mo-1Fe (Ti4211) alloy was investigated. It revealed that after being electrochemical charged at a constant cathodic current density value of 100 mA/cm(2) for 4 h, 8 h and 24 h, needle-like delta-TiHx hydrides were formed in the interior of alpha-Ti phases and at alpha-Ti/beta-Ti interfaces. For the sample being charged for 4 h, alpha-Ti phases near the hydrogen charging direction could be completely transformed into hydrides and formed a hydride layer with an average thickness of 160 mu m. As for the samples being charged for 8 h and 24 h, the thicknesses of the hydride layers were respectively increased to 230 mu m and 380 mu m. Tensile results demonstrated that with the charging time being increased from 0 h to 24 h, the elongation ratio to failure (epsilon(f)) was decreased from 13.2% to 0.6%. The reason for ductile degradation was attributed to the stress concentration effect caused by the preferential cracking of hydride layers. |
