Internal friction and micro-creep measurements were performed with high-purity aluminium bamboo-crystal specimens.The relaxation strength was found to decrease with the decrease of temperature and became zero at about 0.4 T_m(T_m is the melting temperature).This re- flects the occurrence of local disordering in the bamboo boundary region at this temperature. This result conforms to the picture of grain-boundary disordering constructed by atomic simulation studies.
