Restriction data tranferred 2014-07-01T11:10:28-05:00 Original Data Group with Access UIUC Users [automated] Release Date: none Reason: thesis/dissertation thesis/dissertation U of I Only The low temperature lattice thermal conductivity of twinned and untwinned, martensitic and non-martensitic, Indium-Thallium alloys has been measured to probe the effect of twin boundaries on phonon thermal transport. The phonon scattering by electrons, sample surfaces, dislocations, and impurities is accounted for adequately by existing theoretical models. The reduced lattice thermal conductivity seen in the twinned samples is attributed to additional phonon scattering by twin boundaries and, for the polycrystalline samples, by grain boundaries. Phonon scattering by twin boundaries is well represented by the acoustic mismatch model. 3478198 http://hdl.handle.net/2142/29593 en Copryight 1992 Lynn Shomber Mitchell Thermal Conductivity Alloys Indium-Thallium Low temperature thermal conductivity of twinned and untwinned indium-thallium alloys Dissertation / Thesis text Physics Physics University of Illinois at Urbana-Champaign Dissertation Ph.D.
