Abstract：
The monoenergetic slow positron beam was first used to study the crystallization process of metallic glasses. The measurement of Doppler broadening spectra as a function of positron beam energy was performed on the samples of the metallic glass Pd _79.5Ni ₄Si _16.5with various states (i.e., the as-quenched state, structural relaxation states and crystalline states). It is shown that there are a great number of the vacancy-type defects in the as-quenched state sample. Its crystallization process starts at the sample surfaces. The present research indicates that the slow positron annihilation spectroscopy (SPAS) is one of most effective methods for studying the crystallization process of metallic glasses.
