摘要: A non-linear fitting program based on Bevington method is designed to fitthe internal friction temperature spectrum. spectre consisting of utmost six peaks with alognormal distribution in relaxation tabs and an exponential background could be fitted by theprogram. Upon this program, the paramaters bamboo grain boundary peak inpure Al are analyzed quantitatively. It shows that strength decreases thedescending temperature.
