## Description

- description: 'Back stress is an internal stress that develops in materials undergoing
    plastic deformation, arising from dislocation interactions with various microstructural
    features. It plays a crucial role in explaining the Bauschinger effect, typically
    seen in materials subjected to strain path changes. While the deformation behaviour
    of IN718 has been extensively studied, the influence of prestrain on back stress
    evolution in aged IN718 remains unclear. Tension (prestrain)-compression tests
    were conducted on IN718 with varying prestrain to reveal the evolution of the
    back stress. Two approaches were used to quantify back stress: a macroscopic one,
    where the back stress is estimated as half the difference between the maximum
    stress during prestrain and the yield stress during subsequent compression. In
    the second approach, back stress is calculated by measuring the geometrically
    necessary dislocation (GND) density in the deformed microstructures. Both approaches
    are shown to be consistent, and an increase in back stress was observed with increasing
    prestrain. The prestrained samples were characterized utilizing electron backscatter
    diffraction (EBSD) measurement. '
