Calculation of the oxide growth rate of 2-1/4 Cr - 1 Mo steel in air and the subsequent measurement of the strain required to crack the oxide
(Monterey, California; Naval Postgraduate School, 1980-09)
This study examined the growth rate of 2-1/4 Cr - 1 Mo steel in air under isothermal growth conditions. Two oxidizing temperatures were used, 403 degrees and 499 degrees, for five specimens each with oxidizing times varying ...
Application of H infinity method to modern fighter configuration
(Monterey, California. Naval Postgraduate School, 1989-12)
H„ optimal control theory, based on singular value loop shaping, is used to
synthesize a controller for the statically unstable longitudinal dynamics of X-29
aircraft. Two design cases are studied: 2-input 2-output; and ...
The computer simulation and modeling of a flexible missile in 2-D motion.
(Monterey, California. Naval Postgraduate School, 1989)
The development and computer simulation is presented for a bending flexible missile with a rigid-body controller system moving in a 2-D coordinate frame. In this thesis, the dynamic model was developed through the Equivalent ...
Development of a constituitive equation for HSLA-100 at cryogenic temperatures
(1987-12)
HSLA-100 is a 100ksi nominal yield strength steel being developed by the Navy for
Naval shipbuilding applications. To assist in ductile and brittle failure modelling of this low
carbon steel, tensile tests were conducted ...
Effect of chromium addition to the low temperature hot corrosion resistence of platinum modified aluminide coatings.
(1985)
Marine gas turbines face many adverse conditions such as
reduced fuel quality and a salt environment which present
the sulfur, chloride, and sulfates required to initiate and
propagate hot corrosion. A particularly ...
Plastic instability of aluminide and platinum modified diffusion coatings during 1100˚C cyclic testing.
(1985-12)
Platinum modified and unmodified aluminide diffusion
coatings, on a nickel base superalloy (IN-738), were
prepared to test the pre-aluminizing surface roughness
effect on coating oxide scale adherence. A preliminary
study ...
Experimental studies of impulse noise produced by spheres moving through water
(Monterey, California; Naval Postgraduate School, 1980-03)
It is known from previous experiments that freely falling spheres produce sudden noise bursts. The source of this noise is unknown and little is known about the conditions under which it occurs, In an attempt to study ...
Interface characterization of Cu-Cu and Cu-Ag-Cu low temperature solid state bonds.
(1987)
In this study, Auger Electron Spectroscopy (AES),
Scanning Electron Microscopy (SEM) and Energy Dispersive
X-ray (EDX) analysis have been used to characterize the
interface regions of copper to silver and copper to copper
bond ...
Characterization of the structure and substructure of thermally transformation cycled Cu-Zn-Al shape memory alloys
(Monterey, California. Naval Postgraduate School, 1983-06)
Samples of a Cu-Zn-Al shape memory alloy were thermally
cycled up to 10 times, using a differential scanning
calorimeter, between the parent and martensite phases. The
trends of transformation temperature versus number ...
Damping degradation in incramute and sonoston due to low temperature storage.
(1986-12)
Two commercial manganese-copper based alloys, SONOSTON and INCRAMUTE, were evaluated
for their ability to maintain optimum damping capacity with time when stored at room
temperature and 100°C, which represents a temperature ...
