SUMMARY:Rank-one connections and microstructure in single crystals and polycrystals
LOCATION:Hill 705
DESCRIPTION:The talk will describe how nonlinear elasticity can be used to predict micr
 ostructure arising from solid phase transformations in alloys, and survey s
 ome recent results related by the common theme of finding rank-one connecti
 ons between energy wells, these describing possible planar interfaces betwe
 en different phases. The results\nconcern slip and twinning in Bravais latt
 ices, compatibility of martensitic microstructures across polycrystal grain
  boundaries, and remarkable martensitic microstructures\nobserved in the al
 loy Ti76Nb22Al2.\n
