DESCRIPTION:Dr. Anirudh Raju Natarajan\, University of California Santa Ba
 rbara\nModern structural materials used in aerospace and automotive applic
 ations exploit phase transformations to tune material properties. For inst
 ance\, the formation of precipitate phases within a disordered matrix enha
 nces mechanical strength and creep resistance. The design and discovery of
  new structural alloys and processing routes is limited at the macro-scale
  by the lack of rigorous phenomenology and at the atomistic scale by our u
 nderstanding of phenomena such as nucleation\, diffusion and deformation.\
 nIn this talk I will illustrate how first-principles electronic structure 
 calculations coupled with statistical mechanics techniques can be used to 
 inform design choices across length scales. At the atomistic scale\, I wil
 l elucidate the role of order-disorder and structural phase transformation
 s in designing lightweight magnesium alloys and high-temperature refractor
 y alloys. At the mesoscale\, modeling techniques such as the phase-field m
 ethod are invaluable in aiding the design of processing techniques. I will
  describe how inputs to mesoscale models can be rigorously extracted from 
 atomistic simulations through statistical mechanics techniques. As we expl
 ore new frontiers in material chemistries and manufacturing techniques\, t
 he methods and insights from these studies will help guide the design and 
 fabrication of the next generation of engineering alloys.\n\nBio: Anirudh
  is a postdoctoral scholar in the materials department at the University 
 of California\, Santa Barbara. He is interested in the development and app
 lication of first-principles methods to inform phenomenological models for
  the purpose of modeling equilibrium and non-equilibrium processes. Of par
 ticular interest are the structural and diffusive phase transformations in
  alloys. Anirudh received a B.Tech in metallurgical and materials engine
 ering from the Indian Institute of Technology\, Madras\, a M.S in Material
 s Science and Engineering from the University of Michigan\, Ann Arbor and 
 a Ph.D. in Materials from the University of California\, Santa Barbara. \
