Ion beam modification of metals: Compositional and microstructural changes
(Elsevier, 1989)
Ion implantation has become a highly developed tool for modifying the structure and properties of metals and alloys. In addition to direct implantation, a variety of other ion beam techniques such as ion beam mixing, ion ...
Microstructural studies of sputter-deposited TiN ceramic films
(Elsevier, 1989-05-02)
A transmission electron microscopy study was undertaken to characterize the microstructures of TiN thin films that were sputter-deposited onto Cu-Be, alumina and glass substrates. There were no substantial microstructural ...
Similarities in the fracture surface features of borosilicate and polymer glasses
(Kluwer Academic Publishers; Chapman and Hall Ltd. ; Springer Science+Business Media, 1989-10)
Considerable similarity exists between the features on the fracture surfaces of a borosilicate glass and those on the fracture surfaces of polymer thermoset glasses like epoxies and vinyl esters. These features include the ...
Yield loci of anisotropic sheet metals
(Elsevier, 1983)
Four sheet metals, having quite different combinations of R-values and strain-hardening behavior were tested in uniaxial tension, uniaxial (through thickness) compression, balanced biaxial tension (bulge test), and ...
A petrographic thin sectioning technique for evaluating composite materials
(Kluwer Academic Publishers; Chapman and Hall Ltd. ; Springer Science+Business Media, 1989-08)
Characteristics of dislocations at strained heteroepitaxial InGaAs/GaAs interfaces
(The American Institute of Physics, 1989-10-01)
The formation, interaction, and propagation of misfit dislocations in molecular‐beam epitaxial InGaAs/GaAs heterointerfaces have been studied by transmission electron microscopy. With the lattice mismatch less than 2%, ...
Strain and temperature accelerated relaxation in polycarbonate
(John Wiley & Sons, Inc., 1988-11)
The nonlinear viscoelastic behavior of glassy polymers and its relationship to ductile yielding is studied by single- and double-step stress relaxation experiments. In the latter case a small stress relaxation step is ...
Laser-driven micro-explosive bonding of aluminium films to copper and silicon
(Kluwer Academic Publishers; Chapman and Hall Ltd. ; Springer Science+Business Media, 1988-06)
Laser explosive microfabrication was used to bond micrometre-thick aluminium films to both copper and silicon substrates. Bonding was observed in both systems for laser intensities greater than about 1 × 10 9 W cm −2 and ...
A computational framework for modeling irradiation creep and swelling in single crystal nickel
(Elsevier, 1986-06)
A computational framework for modeling irradiation creep and swelling is developed to estimate creep strains, swelling strains and the dose dependent evolution of microstructural characteristics such as dislocation density, ...
