Abstract
The effects of hydrogen on the mechanical properties at room temperatu re of a Ti3Al based alloy Ti-24Al-11Nb-3V-1Mo have been investigated. The results show a parabolic rate relationship between the average hyd rogen concentration of the alloy at constant temperature and charging time. The mechanical properties (ultimate bending strength and deflect ion) decrease with increasing hydrogen content in the alloy. The fract ographic feature indicates that the decrease of the mechanical propert ies is due to the crack nucleation and propagation at the hydride Ti3A lH.
