Description
We report here for the first time the positron annihilation study of quasicrystalline Al86Mn14 alloy. Our study confirms calorimetric results reported earlier, which indicated that, before the crystallisation, the quasicrystalline phase in this alloy goes through a structural relaxation process. The underlying cause of the substantial drop in the line-shape parameter S during the crystallisation process is also considered. (author)
