Abstract

This project proposes a Research Visit of my Master student, Rodrigo Freitas, to be realized at Stanford University under the supervision of Prof. Dr. Wei Cai, with the objective of completing part of the Master's Research Project entitled "Study of Martensitic Phase Transitions in Metallic Alloys" supported by Fapesp grant 2010/13902-4. The general objective of the visit is to enhance the understanding of the kinetics involved in martensitic phase transitions, with special attention given the the role of extended defects such as dislocations. An important issue in this context involves the structural evolution of these dislocations, which are the linear defects that are responsible for the plastic deformation of crystalline solids, along such a phase transition. Prof. Cai is an internationally recognized expert in the computational modeling of such defects, being co-author of a recent text book published by Oxford University Press on this subject. In this way Rodrigo will have a unique opportunity to enhance his knowledge, both of the physics behind the plastic deformation of crystalline solids as well as of the most modern computational modeling techniques, being supervised by one of the leaders of the field.
