Hydrogen absorption into aluminum alloy 2024-T3 during exfoliation and alternate immersion testing
(1998)
Exfoliation and alternate immersion corrosion were investigated in Al alloy 2024-T3 (UNS A92024) uptake during exposure and to correlate it with corrosion characterization. Characterization involved determination of weight ...
THERMODYNAMICS-BASED ALLOY DESIGN CRITERIA FOR AUSTENITE STABILIZATION AND TRANSFORMATION TOUGHENING IN THE FE-NI-CO SYSTEM
(1995)
Transformation toughening has been widely applied in metastable austenitic steels. Recently this toughening mechanism has been extended to ultrahigh strength secondary-hardening martensitic steels, bearing suitable austenitic ...
Thermochemical treatments for protection of steels in chemically aggressive atmospheres at high temperatures
(1999)
Boronizing is a well-known thermochemical treatment process that has found applications in a variety of industries. Boride layers on Fe-alloys present high hardness values (similar to 1900 Hv), good wear properties and are ...
Growth of TiB2 and TiC coatings using pulsed laser deposition
(1997)
Refractory coatings of TiC and TiB2 have been grown by pulsed laser deposition on Si(100) and on X155 steel at various substrate temperatures ranging from 40 degrees C-650 degrees C. A pulsed KrF excimer laser was used ...
Automated material handling and just-in-time
(1998)
Material handling is a very important part of any industry, and with new technological advances this field has become easier to deal with. This article looks at different aspects of what is happening with automation and ...
Nonplanar interfacial cracks in anisotropic bimaterials
(1999)
This paper presents a general approach for the two-dimensional elastic problem of a crack lying along an elliptical interface seperating two dissimilar anisotropic materials. The analysis is based upon the use of the ...
Nanocrystalline growth and diagnostics of TiC and TiB2 hard coatings by pulsed laser deposition
(1999)
Nanocrystalline coatings of TiC and TiB2 were grown by pulsed laser deposition on Si(100) and on X155 steel at low substrate temperatures ranging from 40 degrees C to 650 degrees C. A pulsed KrF excimer laser was used with ...
On the nanocrystalline structure of TiC and TiB2 produced by laser ablation
(1997)
Thin films of TiC and TiB2 have been deposited on silicon substrate by pulsed laser deposition technique, under substrate temperatures 25 - 600 degrees C. Transmission electron microscopy revealed the nanocrystalline ...
Pyrolytic laser-based chemical vapour deposition of TiC coatings
(1995)
TiC layers have been successfully deposited locally on D2 tool steel specimens and miniature industrial tools with the aim to improve their mechanical and chemical surface properties. The deposition process was based on a ...
