| Abstract Scope |
The influence of feedrate on the properties and microstructure of spin-formed aluminum alloy 6061 is explored utilizing microhardness mapping and microtextural analysis via electron backscatter diffraction (EBSD). The varying hardness profiles and microtexture are compared not only between samples spin-formed at various feedrates, but through the thickness of the samples to understand microstructural gradients that could lead to mechanical anisotropy and changes in formability. The resulting hardness data show a clear gradient from the outer mold line to the inner mold line that varies with feedrate and can relate to the imparted strain in the material. The microtextural mapping indicates a slight influence from feedrate, but shows trends through the thickness of the material that suggest varying locationally dependent stress states. The results show for the first time the influences of spin forming on hardness and texture that could be utilized to optimize spin forming processing parameters and mechanical performance. |
