The Effect of Ferrite Content on the Creep of a 12Chromium-2Molybdenum-0.08Carbon, Ferrite-Martensite Steel (Two-Phase).
(1986)
The effect of ferrite content on the creep of a 12Cr-2Mo-0.08C ferrite-martensite heat-resisting steel was investigated. Creep tests were performed at 550, 600, and 650 C for up to 10,000 hr on four steels containing 51, ...
Phase stability of zirconia solid solutions.
(1989)
Using three analytical methods, X-ray diffraction, EDX composition analysis, and thermal expansion, a zirconia rich part of ZrO$\\sb2$-Sc$\\sb2$O$\\sb3$ phase diagram was re-examined. The result shows the tetragonal ...
Integration of Human Error in Structural Reliability Models (Fatigue, Structural Cost, Limit State, Sensitivity Analysis, Failure).
(1986)
Recent structural failure surveys reveal that the actual rates of failure are very different from the theoretical expectations. Because human error is the major cause of this discrepancy, control processes should be designed ...
Assessing the Role of Polydispersity and Cocrystallization on N-Paraffins Crystallizing in N-Paraffin Solutions.
(2009)
Wax deposition in subsea oil pipelines is a major challenge in the petroleum industry. The solid components of these wax-oil gel deposits are primarily n-alkanes. Wax-oil gel properties are a function of the composition ...
Metal-Mold Interfacial Heat Transfer During the Solidification of Metal Castings.
(1985)
The present work identifies the mechanisms of heat transfer at a metal-mold interface during the solidification of a metal casting. It is proposed that in the absence of externally applied pressure such as in die castings, ...
Nonequilibrium Transient Analysis of Nuclear Steam Generators.
(1981)
This thesis describes the development and verification of a nonequilibrium drift-flux steam generator model to simulate and analyze various transients encountered in nuclear plants utilizing light water reactors. The ...
Heat Extraction and Dendritic Growth during Directional Solidification of Single-Crystal Nickel-base Superalloys.
(2011)
Single crystal (SX) growth requires directional solidification (DS) with a sustained thermal gradient in the withdrawal direction. By increasing the thermal gradient, the dendrite structure in nickel-base superalloys is ...
Investigation of optical properties of quantum wells for optoelectronic device applications.
(1989)
The b and offsets of heterostructures are very important parameters for the design of optoelectronic and electronic devices. The Deep Level Transient Spectroscopy (DLTS) technique has been used for the first time to estimate ...
Reconstruction of Strongly Refracting Asymmetric Fields from Interferometric Measurements.
(1980)
A reconstruction method for strongly refracting, asymmetric refractive index fields from optical pathlength measurements has been developed, tested by numerical simulations, and successfully applied to experimental data. ...
Transient Stability Analysis of Large Scale Power Systems Using Energy Methods.
(1983)
The transient stability analysis of large scale power systems is an important problem in power system planning and operation. Social and economical factors have forced electrical utilities to use electric energy from remote ...
