摘要：

Flow studies in extrusion tests revealed that the Pb-Sn eutectic alloy in the snperplastic state yielded velocity fields nearly identical with those obtained using lead. Slight differences observed in the velocity fields were attributed to differences in boundary friction. The test results appear to support the contention thai the flow field within a plastically moving metal or alloy essentially is unique for identical boundary conditions. It is suggested that moderate variations in the properties of the material and in the flow condition will contribute only minor changes in the velocity distribution. Uniqueness is supported by the present results but not proved unequivocally. © 1969 by ASME.
