Atomistic Computer Simulation of Hydrogen Embrittlement

Abstract

Fracture mechanism of hydrogen embrittlement has not been clarified yet, in spite of a lot of studies One of the reasons is due to difficulty of catching directly the evidence of hydrogen. Then, atomic computer simulation is expected to answer this problem. A review of atomistic computer simulation and of results of hydrogen embrittlement is presented A. question whether hydrogen embrittlement is caused by lattice decohesion or enhancement of plastic deformation due to hydrogen is also discussed.
