Effect of a Special ECAP Die Configuration on Microhardness Distributions in Pure Aluminum

摘要：

Experiments were conducted to evaluate the feasibility of using a new ECAP die configuration in which there are arcs of curvature at the intersection of the two channels at both the outer and inner points. The experiments used a configuration in which the radii of curvature were identical at both the outer and inner points since calculations suggest this corresponds to an optimum configuration. Highpurity aluminum was pressed using this special die and hardness measurements were taken on crosssectional planes after pressing. The results show the new die configuration leads to less homogeneity than with conventional ECAP dies.
