A positron annihilation spectroscopy technique was used to investigate the interfacial defects in these nanocrystalline samples.It was found that with a decrease of grain size,the excess volume in a unit volume of interfaces is reduced. By means of accurate density measurement and structural characteristic analyses of the nanocrystalline samples, the interfacial excess volume in the sample is found to be decreasing with reduction of grain size,i.e. a densification of interfaces.This result is in a good agreement with those from the positron annihilation experiments and from other property measurements.
