摘要: Hydrogen transport during the welding of titanium alloy Ti–6Al–4V is analysed. A coupled thermodynamic/kinetic treatment proposed in which driving force for hydrogen migration its chemical potential gradient, turn calculated using Thermo-Calc software package. The model applied to case electron beam Ti–6Al–4V, a simple process presented temperature evolution expected. There thermodynamic accumulation weld pool. However, agreement with limited amount experimental data literature field caused by indicates that account needs be taken degassing from
