Webb29 aug. 2024 · When applying a load to a part, initially the relationship between stress and strain is linear. While the relationship remains linear, it is considered the elastic region of the material. In the elastic region of the material, when the stress is removed, the part returns to its original shape. Webb28 maj 2024 · It was shown that the initial stress and strain state, which can be tailored by an Au interlayer in FePt/Au/FePt trilayers, affect the ordering process and, thus, the magnetic properties. More specific, large compressive strain in the as-deposited FePt layers promote the L1 0 -FePt phase formation. mamajuana by the river
