%X The grain boundary internal friction of a series of Al-Mg alloys afterannealing,quenching has been investigated.Experimental results show that,with increasingof Mg content,the width and relaxation strength of grain boundary internal friction peak de-crease monotonously,the peak position shifts to high temperatures at low Mg content andthen moves back to low temperature;quenching from high-temperature can suppress the grainboundary peak of Al-2.4wt-%Mg alloys but not other alloys with small Mg content.This sup-pressed peak will recover after annealing at an elevated temperature.These phenomena havebeen discussed from three aspects in this paper.
