Extended investigation of porosity in quasicrystals by synchrotron X-ray phase contrast radiography: Part II, in grains of other alloys and structures than AlPdMn

The results show that the presence of facetted micrometric pores is not restricted to icosahedral quasicrystals. Otherwise the part played by these pores to their actual existence and stability remains as questionable. The samples contain pores or not independently of the growth method, which does not seem to have an influence on the pores. Since pores were only observed in samples of the Al-rich phases this element could be an important ingredient for the formation of pores during the solidification process as it has been suggested in Part I.
