DESCRIPTION: Polycrystalline Ni-based superalloys are vital materials for d
 isks in the hot section of aerospace and land-based turbine engines due to
  their exceptional microstructural stability and strength at high temperat
 ures. In order to increase operating temperatures and hold times in these 
 engines\, hence increasing engine efficiency and reduction of carbon emiss
 ions\, creep properties of these alloys becomes increasingly important. Mi
 crotwinning and stacking fault shearing through the strengthening g’ pre
 cipitates are important operative mechanisms in the critical 600-800°C te
 mperature range. Atomic-scale chemical and structural analyses indicate th
 at local phase transformations (LPT) occur commonly during creep of supera
 lloys. Furthermore\, the important deformation modes can be modulated by L
 PT formation\, enabling a new path for improving high temperature properti
 es.\nSpeaker: Professor Michael J. Mills
