...-boundary fracture resistance ( Ref 23 , 25 ). Tying up similar deleterious species at other interfaces may change the microstructural fracture mode. For example, 7075-T651, an Al-Mg-Zn-Cu alloy, fails by IG fracture. Evidence indicates that this may be a hydrogen embrittlement process along grain...
