... Abstract Porosity in aluminum is caused by the precipitation of hydrogen from liquid solution or by shrinkage during solidification, and more usually by a combination of these effects. Nonmetallic inclusions entrained before solidification influence porosity formation and mechanical properties...

... precipitates in preexisting voids in the metal. Pressure is built up in the voids, adding to the effect of externally applied stress. Thus, the applied stress for fracture metal is reduced. The problem with the pressure theory appears to be that an uncharacteristically high hydrogen fugacity is required...
