摘要: Abstract The diffusion kinetics of hydrogen in Ti-6Al-4V alloy was investigated by the gaseous charging at initial pressures 0.012, 0.04 and 0.07 MPa temperatures 800, 850 900 °C. results show variation average concentration with time exhibits an exponential characteristic relationship different or temperatures. process is controlled atoms alloy. Based on solution equation, apparent activation energy estimated to be 32.80 kJ/mol. This β phase
