“…Many studies (7) (8) on powder compaction process by numerical analysis have been done to predict density distribution of the material, and several constitutive equations have been proposed. As to the analysis of rolling of solid material, Karman's equation (9) is well-known.…”

Metal flow and strain distribution in the flat rolling of Sn-Pb alloy powder are experimentally analyzed by the modified visioplasticity method. The alloy powder is packed in a container of 10mm square made of aluminum foil and rolled up to 80% reduction in height. After the interruption of rolling, distorted shapes of the powder particles are measured experimentally. It is observed that the difference of reduction has considerable influence on the flow and strain distribution. As a result, it is made clear that the deformation of powder particles can be classified into three areas; (A) pore decreasing area, (B) particle bonding area and (C) plate forming area.
