This investigation has the objective of improving the                      accuracy of constitutive models for the hot working of metals.                  Currently, the simulation of complex forming processes, such as                 extrusion, forging and superplastic forming, has been modeled                   using finite element methods and constitutive equations.                        However, there is a lack of proper data upon which to base these                equations.  The rate dependent flow of metals will be                           systematically investigated by means of detailed constant-                      structure experiments on high-purity, polycrystalline aluminum.                 The unique data so generated should lead to more appropriate flow               equations that incorporate internal variables in their                          formulation.
