Abstract Scope |
The present investigation is based on the study of microstructural evolution in pure copper (Cu) and copper-8 wt.% aluminium (Cu8Al) alloy at various strain by interrupted micro-tensile tests. X-ray diffraction (XRD) and scanning electron microscopy (SEM) are performed to acquire the initial and final microstructural details of the samples. The microstructural evolution with deformation is analysed using electron backscattered diffraction (EBSD) for both Cu and Cu8Al alloy. We have observed the effect of geometrically necessary dislocation (GND) density inside the grain with varying grain orientation and near grain boundaries as well as twin boundaries. We have noticed that GND values near boundaries does not behave monotonically for Cu and Cu8Al. We have also discussed about various dislocation interaction with grain boundaries and twin boundaries in Cu and Cu8Al. In addition, we have analysed our results in terms of Schmidt factors and grain reference orientation deviation (GROD). |
