Dislocation generation around cylindrical pores

The formation of dislocation arrays reflecting the crystallographie symmetry of the surface pores formed by a mechanism of pitting corrosion was observed. The hypotheses developed in connection with the origination of dislocations around cylindrical pores by the effect of capillary forces led to process parameters whose estimated values agree well with those experimentally obtained. It is pointed to the importance of this process for the shrinkage during sintering.
