摘要：
The effects of hydrogen on the deformation mechanism of < 0 0 1 >-oriented single crystals of Hadfield steel were studied under tension at temperatures of 77 and 300 K. An increase in intensity of twinning was observed for samples charged with hydrogen, and it is assumed that this is the reason for the increase in elongation to fracture. Despite the high elongation to failure, the fracture surfaces displayed a brittle component. (c) 2010 Acta Materialia Inc. Published by Elsevier Ltd. All rights reserved.
