      abstract     = {It is now generally admitted that pores are intriguing
                      special features of quasicrystals. Therefore, we have
                      performed an 'in situ' and real time observation of the pore
                      evolution during directional solidi. cation and melting
                      cycles of an icosahedral Al-Pd-Mn bi-grained sample, by
                      synchrotron X-ray radiography. Rather surprisingly, no pore
                      was observed to grow during the solidi. cation stages.
                      Nucleation and growth of pores were first seen during
                      melting. These pores were subsequently shrinking either just
                      before being absorbed or during resumption of directional
                      solidi. cation. It is concluded that the vacancy origin of
                      pores is certainly valid whereas the vacancy
                      supersaturation, needed thereby to explain their growth,
                      would be more probably related to the peculiar structure of
                      quasicrystal than to the destruction of the thermal
                      equilibrium.},
