Temperature dependent plastic deformation of

This thesis investigates the temperature-dependent plastic deformation of magnesium through micro-pillar compression, addressing critical challenges in the mechanical behavior of this metal at varying temperatures. The objective of the study is to analyze how temperature influences the deformation mechanisms and yield strength of magnesium. To achieve this, a series of micro-pillar compression tests were performed across a range of temperatures, allowing for detailed observations of the material's response to stress. The methodology involved the fabrication of micro-pillars using micro-machining techniques, followed by in-situ compression tests under controlled temperature conditions. The results obtained demonstrate a significant correlation between temperature and the flow stress of magnesium, indicating that increased temperatures lead to enhanced ductility and reduced strength. The findings suggest that the activation of specific deformation mechanisms, such as twinning and dislocation movement, plays a crucial role in this behavior. Overall, this research contributes to a deeper understanding of the mechanical properties of magnesium and highlights the importance of temperature in materials science, with implications for its applications in various engineering fields.
