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 ...
Phase formation in ion‐irradiated and annealed Ni‐rich Ni‐Al thin films
(The American Institute of Physics, 1991-02-15)
Phase formation was studied in ion‐irradiated multilayer and coevaporated Ni‐20 at. % Al films supported by Cu, Mo, and Ni transmission electron microscopy (TEM) grids. Irradiation with either 700‐keV Xe or 1.7‐MeV Xe, to ...
The heat‐of‐mixing effect on ion‐induced grain growth
(The American Institute of Physics, 1991-08-01)
Irradiation experiments were conducted on multilayer (ML) and coevaporated (CO) thin films in order to examine the role that the heat‐of‐mixing (ΔHmix) has in ion‐induced grain growth. Room‐temperature irradiations using ...
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.%) ...
Transition from lateral to transverse phase separation during film co‐deposition
(The American Institute of Physics, 1991-11-11)
We report observations of two distinct types of phase‐separated microstructures in co‐deposited Al‐Ge films. In the initial stages of growth, lateral phase separation is observed, with a temperature dependence consistent ...
