Formatted abstract
In situ synchrotron radiation revealed how the scavenging of oxygen by yttrium hydride (YH2) occurred in powder metallurgy commercially pure Ti (CP-Ti) and Ti–6Al–4V. YH2 decomposes at >900 °C in CP-Ti and at >1100 °C in Ti–6Al–4V. Elemental Y coexists with Y2O3 in both CP-Ti and Ti–6Al–4V up to 1300 °C. Ex situ analytical means further confirmed that the scavenging product is Y2O3. Together with available diffusion data, mechanisms are proposed to understand the decomposition of YH2 and the scavenging of oxygen in CP-Ti and Ti–6Al–4V.
