Stanford, CA
Joined November 2016
Intergranular cracks propagate either through the brittle extension of an existing crack or through coalescence with secondary cracks ahead of the crack front. Secondary cracks form via void nucleation and growth at grain boundaries and preferentially initiate at high-angle GBs

Coherent twin boundaries are not significant locations for hydrogen segregation, regardless of sample strain.

We find that: Under elastic strain or small plastic strains, there is no preferential hydrogen segregation to particular grain boundaries. Under higher plastic strains, hydrogen preferentially segregates to high angle boundaries (∼25-55 degrees misorientation).

We developed an in-situ scanning probe strain stage to observe hydrogen segregation at different grain boundaries (misorientation angle, twin boundaries) under strain. synchrotron transmission X-ray microscopy (TXM) is used to observe the dynamics of fracture at these boundaries
