文摘
- •
Hydrogen induced cracking in TRIP-assisted steel is evaluated by EBSD.
- •
Tensile tests were conducted on notched hydrogen saturated samples.
- •
Crack initiation occurs by a H-Enhanced Interface DEcohesion (HEIDE) mechanism.
- •
Crack propagation involves growth and coalescence of small cracks.
- •
Propagation is governed by the characteristics of phases on the crack path.
