Computer program for the kinetics and populations in a xenon fluoride laser
(Monterey, California. Naval Postgraduate School, 1979-12)
To highlight in a qualitative manner the kinetics of an excimer laser, a simple computer model for calculating the species populations in a KrF laser cavity is developed; subsequently a computer program originally developed ...
A preliminary investigation of the corrosion and stress-corrosion susceptibility of thermomechanically processed high magnesium aluminum magnesium alloys
(Monterey, California. Naval Postgraduate School, 1981-09)
The stress corrosion cracking susceptibility and general corrosion characteristics of four thermomechanically processed high-Magnesium, Aluminum-Magnesium alloys were evaluated and compared to those of 7076-T6.
Results ...
The effects of environment and dwell on high temperature fatigue crack growth of 2 1/4 Cr - 1 Mo steel.
(Monterey, California. Naval Postgraduate School, 1983-06)
The effects of the environment and dwell periods on
fatigue crack growth rates at 525°C for both annealed and
normalized and tempered 2 1/4 Cr - 1 Mo steel in High
Strain Fatigue (HSF) and Linear Elastic Fracture ...
The heat treatment response of thermomechanically processed M-50 steel
(Monterey, California. Naval Postgraduate School, 1983-12)
The heat treatment response of M-50 steel, thermomechanically processed by warm rolling, was compared to that of the same material in a conventional, spheroidize-annealed condition. Warm rolling of M-50 produces markedly ...
An investigation of the mechanical properties of warm rolled aluminum-17.5 weight percent copper alloy
(1976)
An aluminum-17 . 5 weight percent copper alloy was warm rolled
to achieve refinement of the microstructure . This refined
microstructure consisted of finely dispersed intermetallic Al^Cu
particles with an average size ...
Transmission electron microscopy study of subgrain strengthening of cartridge brass.
(Monterey, California. Naval Postgraduate School, 1976-12)
The development of substructure in cartridge brass, subjected to cold rolling followed by warm annealing, is characterized as a function of annealing temperature and true strain. Substructure develops and becomes refined ...
Friction stir processing of AS-CAST AA5083 Superplastic response
(Monterey, California. Naval Postgraduate School, 2009-06)
Plates of continuously cast AA5083 were subjected to friction stir processing (FSP) by three overlapping plunge and traverses. The FSP used a threaded pin tool with a pin diameter of 3 mm, pin length of 3 mm and a shoulder ...
A microstructural and mechanical property correlation of friction stir processed nickel aluminum bronze
(Monterey, California. Naval Postgraduate School, 2004-09)
Friction Stir Processing (FSP) is novel technique for localized modification of the surface layer of materials. FSP produces high local strains, strain rates and local temperatures that are 0.8 - 0.9 Tm, where Tm is the ...
Modeling of thermal and mechanical effects during friction stir processing of nickel-aluminum bronze
(Monterey, California. Naval Postgraduate School, 2004-09)
Friction Stir Processing (FSP), although relatively simple in concept, results in an extremely complex thermomechanical treatment to the material being processed. Previous studies of FSP have shown that the process results ...
Grain size control in AA5083: thermomechanical processing and particle stimulated nucelation
(Monterey, California. Naval Postgraduate School, 2004-06)
"Superplastic forming is an emerging industrial technology that allows the production of complex shapes in metallic materials including aluminum. A critical characteristic of materials that are capable of sustaining ...
