Experimental determination of transformation enthalpies of metastable phase transitions in ion-irradiated NiAl3
(Elsevier, 1991-07-01)
A novel experimental technique has been developed by which metastable phase transformations in thin films may be investigated. The technique is demonstrated by the determination of the enthalpies of transformation of two ...
Ion-induced grain growth in multilayer and coevaporated metal alloy thin films
(Elsevier, 1991-07-01)
Irradiation experiments were conducted on multilayer (ML) and coevaporated (CO) thin films in order to examine the role that the heat-of-mixing ([Delta]Hmix) has in ion-induced grain growth. Room-temperature irradiations ...
Hardness and friction of N2+ and Al+ implanted B4C
(Elsevier, 1991-07-01)
Surfaces of boron carbide (B4C) were implanted with 200 keV N2+ or 100 keV Al+ ions to a dose of 8 x 1017 cm -2. Ultralow load indentation via the Nanoindenter was used to determine the changes in surface hardness and ...
Oxide formation and anodic polarization behavior of thin films of amorphous and crystalline Fe---Cr---P alloys prepared by ion beam mixing
(Elsevier, 1991-07-01)
An experimental program has been conducted to determine the effect of phosphorus on the corrosion and passivation behavior of Fe---Cr---P alloys. Chemically homogeneous 60 nm films of Fe---10Cr---xP (x from 0 to 35 at.%) ...
The Michigan Ion Beam Laboratory for Surface Modification and Analysis
(Elsevier, 1989-04-02)
The Michigan Ion Beam Laboratory for Surface Modification and Analysis was established in October of 1986 for the purpose of advancing our understanding of ion-solid interactions on both the fundamental and applied levels. ...
Synthesis and properties of microlaminate structures by ion beam assisted deposition
(Elsevier, 1993)
Films of Al, Al2O3, Mo and MoSix were formed by ion beam assisted deposition (IBAD) at R ratios between 0.004 and 0.1 and film thicknesses between 150 and 1100 nm. Al films were crystalline with a strong (111) fiber texture ...
Automatic iterative fitting of Rutherford backscattering spectra from multielement samples
(Elsevier, 1985-12)
A computer code (BASF) has been constructed to perform automatic iterative fitting of Rutherford backscattering spectra using only the experimental spectrum and the parameter set defining the experiment. The code may be ...
Metastable phase formation by ion beam mixing
(Elsevier, 1987-04-03)
There are essentially four basic types of metastable alloys which may be formed through heavy ion irradiation of crystalline structures: amorphous phases with no long range order; crystalline phases with structures different ...
Grain growth and phase morphology in ion beam mixed, two phase Ni---Al and Ni---Cr---Al alloys
(Elsevier, 1989-03-02)
Multilayers of Ni---21Al and Ni---20Cr---10Al were subjected to ion beam mixing using 350 keV Ni+ ions and/or thermal annealing at 440[deg]C to study the development of grain growth and phase morphology. Two film thicknesses ...
