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 ...
Thermomechanical behavior of monolithic Sn-Ag-Cu solder and copper fiber reinforced solders
(Monterey, California. Naval Postgraduate School, 2005-09)
Solder joints provide both electrical and mechanical interconnections between a silicon chip and the packaging substrate in an electronic application. The thermomechanical cycling in the solder causes numerous reliability ...
An experimental study of steady state high heat flux removal using spray cooling
(Monterey California. Naval Postgraduate School, 2004-12)
Spray cooling is a promising means of dissipating large steady state heat fluxes in high density power and electronic systems, such as thermophotovoltaic systems. The present study reports on the effectiveness of spray ...
Numerical prediction of the impact of non-uniform leading edge coatings on the aerodynamic performance of compressor airfoils
(Monterey, California. Naval Postgraduate School, 2004-06)
A computational fluid dynamic (CFD) investigation is presented that provides predictions of the aerodynamic impact of uniform and non-uniform coatings applied to the leading edge of a compressor airfoil in a cascade. Using ...
Design, fabrication, and testing of a scalable series augmented railgun research platform
(Monterey, California. Naval Postgraduate School, 2006-03)
The design and material properties of rails and projectiles are critical to the success of the Navy railgun. This thesis addresses the design, fabrication, and testing of a scalable square bore electromagnetic railgun. ...
Using x-ray diffraction to assess residual stresses in laser peened and welded aluminum
(Monterey, California. Naval Postgraduate School, 2011-12)
This thesis examines the interplay of residual stress distributions caused by welding and laser peening of marine aluminum alloy 5083. Residual stresses at welds in this alloy can cause fatigue and stress corrosion cracking ...
Horizontal steering control in docking the ARIES AUV
(Monterey, California. Naval Postgraduate School, 2003-12)
To keep the operational cost down and increase the mission time with minimum human intervention, autonomous recovery or docking operation of an Autonomous Underwater Vehicle (AUV) is required. Central to the successful ...
The effects of isothermal deformation and annealing on the microstructure of nickel-aluminum-bronze in relation to the friction stir process
(Monterey, California. Naval Postgraduate School, 2003-12)
The FSP of Nickel Aluminum Bronze is a novel approach to enhance the microstructural properties of the material through a shear deformation process. This thesis examines the effect on microstructure of isothermal annealing ...
Grain size control by thermomechanical processing (TMP) the role of dispersed particles
(Monterey, California. Naval Postgraduate School, 2003-09)
Superplasiticity in Aluminum alloys allows for the economical forming of components of complex shapes while retaining the high-strength and stiffness-to-weight ratios characteristic of alloys used in automotive, aerospace ...
