As a result, it is found that the R-type specimen method enables to evaluate the extremely high superplastic elongation of the commercial 7475 alloy using a furnace with a common length. The elongation of the R-type specimen decreases with an increase in the radius of the R-part below a certain value, while it increases over that value.
