Abstract

 Magnesium (Mg) alloys are attractive as structural materials due to their light weight and high specific strength. It is well known that Mg alloy has hexagonal close-packed (HCP) structure and only basal slip
or twinning can operate during plastic deformation because critical resolved shear stresses of the other slip
systems such as pyramidal or prismatic slips are much higher than the basal slip. Thus sometimes characteristic
fracture surfaces are formed during stress corrosion cracking (SCC) or fatigue crack propagation (FCP) in Mg
alloys, where many parallel lines are formed. These lines are different from so-called fatigue striations, because
they are formed even under sustained load condition of SCC. Consequently, electron back scattered diffraction
(EBSD) technique was applied on the fracture surface, and the formation mechanism of parallel lines was
investigated. EBSD-assisted fractography had revealed that the characteristic parallel lines were formed due to
the operation of basal slips, not twining. It is considered that hydrogen-enhanced localized plasticity (HELP)
mechanism had been activated under corrosive environment.
