| Abstract Scope |
By following varying deformation paths, e.g., a linear path to a final equibiaxial strain value versus bilinear deformation with uniaxial loading followed by nonequal biaxial loading, the same final strain state can be achieved. However, the stress state that the material is subjected to is considerably different due to the varying deformation. This is of interest in a growing field of stress superposition to improve formability and final part properties in metal forming applications. For example, this work may be applicable to forming patient-specific, trauma fixation hardware with differing strength and weight reduction requirements in various regions. In this paper, equibiaxial experimental tests were performed on a custom fabricated cruciform machine with the goal of investigating martensitic phase transformations in stainless steel 316L subjected to varying deformation paths. A novel cruciform specimen geometry was designed in collaboration with the National Institute of Standards and Technology to achieve large strain values in the gauge region to promote martensitic transformations. Digital Image Correlation was utilized to measure surface strains in-situ. A scanning electron microscope was used to measure the amount of martensitic transformation in the samples. |
