Journal ArticleDOI
Metastable phase formation and enhanced diffusion in f.c.c. alloys under high dose, high flux nitrogen implantation at high and low ion energies
TL;DR: The use of elevated target temperatures near 400 °C during high flux ion implantation of N2+ at energies ranging from 60 keV to 0.4 keV leads to a metastable, f.c. high nitrogen solid solution phase induced in austenitic (f.c.) Cr-containing stainless steels.
Journal ArticleDOI
A Model for the Nanodomains in Polymer‐Derived SiCO
TL;DR: In this paper, the authors present a model for these nanodomains, which is consistent with the nuclear magnetic resonance (NMR) data and with the phenomenological properties of SiCO (high resistance to creep and viscoelastic behavior).
Journal ArticleDOI
Phase and composition depth distribution analyses of low energy, high flux N implanted stainless steel
Orhan Öztürk,D. L. Williamson +1 more
TL;DR: The phase and composition depth distributions of a low-energy (0.7 keV), high-flux (2.5 mA/cm2) implanted fcc AISI 304 stainless steel held at 400 °C have been investigated by stepwise Ar+ beam sputter removal in conjunction with conversion electron Mossbauer spectroscopy and x-ray diffraction (XRD).
Journal ArticleDOI
Structural, defect, and device behavior of hydrogenated amorphous Si near and above the onset of microcrystallinity
TL;DR: In this article, high-hydrogen-diluted films of hydrogenated amorphous Si (a-Si:H) 0.5-2.5 μm in thickness and optimized for solar cell efficiency and stability, are found to be partially microcrystalline (μc) if deposited directly on stainless steel (SS) substrates but are fully amomorphous if a thin n layer of a-Si or μc-Si was first deposited on the SS.
Journal ArticleDOI
Effect of austenitic stainless steel composition on low-energy, high-flux, nitrogen ion beam processing
TL;DR: In this paper, a collection of 16 metals with the face-centered-cubic (fcc) crystal structure, including stainless steels, Fe-Ni alloys and pure Ni, have been subjected to the same nitrogen ion beam processing conditions to examine the role of alloy composition in the surface modification behavior.
