Abstract
We present the results of modeling porous cylindrical blanks for open-die forging. We have found that for each size and type of the porous blanks, there are optimal ratios of the initial porosity to the initial clearance between the dies which ensure both complete densification of the blanks and a minimum amount of the material wasted as flash.
