Journal ArticleDOI
Nanoindentation and the indentation size effect: Kinetics of deformation and strain gradient plasticity
TL;DR: In this article, a study of the indentation size effect (ISE) in aluminum and alpha brass is presented, where rate effects are characterized in terms of the rate sensitivity of the hardness, where H is the hardness and e eff is an effective strain rate in the plastic volume beneath the indenter.
Journal ArticleDOI
Grain-size-dependent thermal conductivity of nanocrystalline yttria-stabilized zirconia films grown by metal-organic chemical vapor deposition
Guido Soyez,Jeffrey A. Eastman,L. J. Thompson,G. R. Bai,Peter M. Baldo,A.W. McCormick,Ronald J. DiMelfi,Abdelmageed Elmustafa,Mwilwa F. Tambwe,Donald S. Stone +9 more
TL;DR: A grain-size-dependent reduction in the room-temperature thermal conductivity of nanocrystalline yttria-stabilized zirconia is reported for the first time as discussed by the authors.
Journal ArticleDOI
Experimental and numerical investigation of the plunge stage in friction stir welding
TL;DR: In this paper, a 3D finite element-based model of the plunge phase was developed using the commercial code ABAQUS to study the thermomechanical processes involved during the plunge stage.
Journal ArticleDOI
Indentation size effects in the nano- and micro-hardness of fcc single crystal metals
Zong Zong,Jun Lou,O. O. Adewoye,O. O. Adewoye,Abdelmageed Elmustafa,F. Hammad,F. Hammad,Winston O. Soboyejo +7 more
TL;DR: In this article, the results of the experimental study of nano-and micro-indentation size effect on selected (0.0.1) oriented face-centered cubic (fcc) crystals (Ni, Au and Ag) are elucidated.
Journal ArticleDOI
Nanoindentation Investigation of HfO2 and Al2O3 Films Grown by Atomic Layer Deposition
Kandabara Tapily,Joseph E. Jakes,Joseph E. Jakes,Donald S. Stone,Donald S. Stone,Pragya R. Shrestha,Diefeng Gu,Helmut Baumgart,Abdelmageed Elmustafa +8 more
TL;DR: In this paper, the elastomechanical properties of high-k materials such as HfO 2 and Al 2 O 3 on (100) p-type Si wafers were investigated using nanoindentation and continuous stiffness method.
