Abstract
The effects of hydrogen on the deformation of a BCC Ti alloy surrounding na noindentations are examined using scanning probe microscopy. The surface de formation patterns surrounding indentations with 2600 ppm hydrogen are sign ificantly less than with 140 ppm hydrogen. The reduced pileup is attributed to hydrogen reducing the ability for cross slip to occur. (C) 2001 Acta Ma terialia Inc. Published by Elsevier Science Ltd. All rights reserved.
