Her research interests focus on correlating deformation response of metals and alloys with microstructure. Her group has been using both bulk and micro-deformation techniques along with microscopy to investigate the evolution in microstructure with deformation and quantify the effect of dominant microstructural features on mechanical behavior. They also carry out both Molecular Dynamics (MD) and Dislocation Dynamics (DD) simulations to investigate deformation behavior.

Titanium and its alloys are extensively used for aerospace and biomedical applications due to their high specific strength – even at elevated temperature, and excellent corrosion resistance. Due to its hexagonal crystal structure, alpha titanium is highly anisotropic. Hence it is essential to understand the role of crystallographic orientation and texture in deformation. In this poster, we will present results from bulk deformation and nanoindentation experiments, where we have investigated the role of orientation and of grain interaction on deformation. We show that both orientation and near neighbor interactions play an equally important role in the deformation of polycrystals. We further show that boundaries between hard and soft grains are significantly harder than boundaries between soft grains due to greater incompatibility in deformation between hard and soft grains. In the last five minutes of my talk, she will present some results from her ongoing Dislocation Dynamics simulation studies of deformation of the ferrite phase during wire drawing of pearlitic steel..
