| Abstract Scope |
Incremental forming techniques rely on strain paths that may be radically different than traditional methods. Importantly, the final properties of the metal are rarely independent from the strain history associated with the processing method: understanding differences between representative strain histories is key to advancing incremental forming techniques. This work seeks to relate the geometry, microstructure, and properties of mild steel cylinders to the strain history resulting from two forming methods: spin forming and deep drawing. Experimental results indicate distinct microstructures arising from the two methods: spin forming produces microstructures with elongated, dislocated grains with edge-to-edge variation, while drawing produces dislocated grains with variation from center to edge. Corresponding changes in the local hardness and mechanical properties were measured. These data are expected to facilitate a discussion of material property variation which may be rationalized through consideration of the local strain gradients arising from each method. |
