Understanding the Interaction Between Grain Boundaries and Precipitates in Ni-Al Using Molecular Dynamics
Author: Rachel Louise Morrison
Publisher:
ISBN:
Category : Grain boundaries
Languages : en
Pages : 92
Book Description
This thesis investigates the interaction between gamma' precipitates and grain boundaries in a Ni-Al system during deformation. This interaction is investigated using molecular dynamics, and gamma'/boundary configurations were built to investigate how the orientation, size, and interaction of gamma' change the deformation behavior of the grain boundary. The gamma' aided in nucleating defects (i.e., dislocations) that contributed to the boundary sliding mechanism. By increasing the size of precipitates that bisect the boundary, the boundary becomes stronger, whereas increasing the size of precipitates adjacent to the boundary makes the boundary weaker. Additionally, the interaction of multiple gamma' plays a role in grain boundary sliding behavior. Low concentrations of gamma' produce sliding dominated by atomic shuffling, whereas high concentrations of gamma' produce sliding dominated by dislocation emission. More work is needed to investigate the effects of temperature, initial defects, and different grain boundary configurations on sliding behavior.

Book Description
In recent decades scientists and engineers around the globe have been responding to the requirement of high performance materials through innovative material research and engineering. The ever increasing demand on quality and reliability has resulted in some dazzling technological achievements in the area of advanced materials and manufacturing. The purpose of this book is to bring together significant findings of leading experts, in developing and improving the technology that supports advanced materials and process development. From gold nano-structures to advanced superalloys, this book covers investigations involving modern computer based approaches as well as traditional experimental techniques. Selected articles include research findings on advances made in materials that are used not only in complex structures such as aeroplanes but also in clinical treatments. It is envisaged that it will promote knowledge transfer across the materials society including university students, engineers and scientists to built further understanding of the subject.
