Abstract
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.
