Abstract
Studies have been made of the behaviour under compression of materials which exhibit plastic deformation at normal temperatures, as exemplified by indium and lead. In particular, attention has been focused on the effects of die-wall friction and on the influence of the relative volume. The die-wall friction effects produced by a solid plug of the material were compared with those produced by a particulate fill of the same material when compressed under similar conditions, and a correlation of these effects with the shear strength of the material was made. A theoretical equation relating relative volume at either end of the compact is suggested.
