An advanced calculation has been completed by computer for studing Al and its alloys. In doing so, both parameters of grain boundary relaxation and three parameters of background internal friction can be derived from single experimental internal friction curve containing one relaxation, without acquiring any points from experimental background curve in advance. If two relaxation spectra are considered in experimental curve, thirteen parameters may be derived from single experimental curve by computer technique. In this paper, relaxation strength is considered as function of temperature.
