Precipitation, recovery and recrystallization under static and dynamic conditions for high magnesium aluminum-magnesium alloys
(1980-03)
Previous studies of the mechanical behavior of warm rolled
high magnesium aluminum-magnesium alloys have shown that excellent
tensile properties can be developed in these materials.
Several questions raised in these ...
An investigation of the hot corrosion protectivity behavior of platinum modified aluminide coatings on nickel-based superalloys.
(Monterey, California: U.S. Naval Postgraduate School, 1987-03)
The adverse operating environments encountered by
marine gas turbine components has necessitated the
development of various protective coating systems.
Diffusion aluminide coatings have been used successfully for
many ...
The effect of thermomechanical processing variables on ductility of a high-Mg, Al-Mg-Zr alloy.
(1986)
In previous research on thermomechanically processed high - Mg,
\1 - Mg alloys, yield strengths of 276 MPa (40 ksi) were retained after
simulated superplastic forming, but ductility at ambient temperature
varied from ...
The effects of simulated welds on HY-130 cast and wrough plate and weld microstructures
(1981)
The microstructure and hardness of simulated welds in HY-130
cast plate, wrought plate and weld filler metal are investigated.
The dependence of these quantities on the austenitizing temperature
and the tempering provided ...
Fatigue characteristics and microstructural analysis of thermomechanically-processed, high-magnesium aluminum-magnesium alloy
(1981-06)
This research was an investigation of the fatigue characteristics
of warm rolled high-magnesium aluminum-magnesium
alloys. Particular emphasis was placed on study of the
microstructural changes which occur during cyclic ...
Effect of strain and strain rate on the microstructure of a superplastically deformed Al-10%Mg-0.1%Zr alloy.
(1985-06)
The deformation characteristics of two therraoraechanically
processed, high-Magnesium, Aluminum-Magnesium-Zirconium
alloys were investigated. The processing included warm
rolling at 300°C to 90-95% reduction. Tension ...
Effect of temperature and strain rate on microstructure of a deformed superplastic Al-10%Mg-0.1%Zr alloy
(1985-06)
Development of microstruc ture during thermomechanical
processing of an Al-10 %Mg-0 .l%Zr alloy was examined in the
initial portion of this research. The thermomechanical
processing involved solution treating, hot working ...
A study of the effect of interrupted quenches on a thermomechanically processed high carbon steel
(Monterey, California. Naval Postgraduate School, 1982-10)
The effects of short quench interruptions on the percentage
retained austenite and the hardness and microstructure
were investigated for AISI 52100 steel. Effects were observed
for two starting microstructures : an ...
Thermomechanical processing of M-50 steel.
(Monterey, California. Naval Postgraduate School, 1983-06)
Thermomechanical processing of AISI M-50 bearing steel was
accomplished by an initial austenitize and quench followed by
reheating and warm-rolling to a true strain of 2.0. Warm-rolling
was successfully conducted at ...
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 ...
