Structure And Deformation Of Carbyne Deposited On A Nickel Substrate, Abigail Eaton
Structure And Deformation Of Carbyne Deposited On A Nickel Substrate, Abigail Eaton
Mechanical Engineering Undergraduate Honors Theses
Carbyne is a nanomaterial of great interest due to its ability to withstand high forces similarly to other carbon allotropes such as graphene or carbon nanotubes. However, it is currently difficult to synthesize and maintain without the assistance of a composite material substrate that the carbyne can be integrated with, which will affect its reaction to varying conditions. This thesis focuses on studying the effects of carbyne on a nickel surface and its mechanical properties to predict its future usages and potential for applications in varying fields. We perform a three-point bending test simulation using molecular dynamics with pure Ni …
Development Of Oxide-Dispersion-Strengthened Nickel-Based Super Alloy Powders For Additive Manufacturing, Sizhe Huang
Development Of Oxide-Dispersion-Strengthened Nickel-Based Super Alloy Powders For Additive Manufacturing, Sizhe Huang
Graduate Theses, Dissertations, and Problem Reports
Oxide-Dispersion-Strengthened (ODS) Nickel-Based superalloy has been drawn a huge attention and developed with good oxidation resistance, corrosion resistance and high creep strength. It has been considered as critical materials for Additive Manufacturing (AM). The quality and the efficiency of fabrication methods of ODS limits the performance of itself on AM. The development of new type of ODS, new methodologies and evaluation techniques are required if the enhanced quality of ODS and enhanced efficiency of fabrication are to be achieved. Of the current fabrication techniques for AM, Gas Atomization (GA) is widely used since they can generate spherical powders with high …
Structural Tailoring Of Nanoporous Metals And Study Of Their Mechanical Behavior, Lei Wang
Structural Tailoring Of Nanoporous Metals And Study Of Their Mechanical Behavior, Lei Wang
Theses and Dissertations--Chemical and Materials Engineering
Nanoporous (np) metals and alloys are the subject of increasing research attention due to their high surface-area-to-volume ratio. Numerous methods exist to create np metals, with dealloying being a common approach. By dissolving one or more elements from certain alloy systems, porous structure can be generated. Utilizing this method, multiple np metals, including np-Ni, np-Ir, and np-Au were created. By carefully adjusting precursor type and dealloying conditions for each system, nanoporous Ni/Ir/Au with different morphologies and even controllable ligament/pore size were achieved.
The mechanical behavior of porous materials is related to their fully dense counterparts by scaling equations. Established scaling …
Ferromagnetic Alloys In The System Cu-Mn-Zn, W. Michael Yim
Ferromagnetic Alloys In The System Cu-Mn-Zn, W. Michael Yim
Bachelors Theses and Reports, 1928 - 1970
The purpose of this investigation is to determine whether ferromagnetic alloys exist in the ternary system Cu-Mn-Zn analogous to the other Heusler alloys. The work in this thesis is a preliminary investigation on these alloys using a common metallographic research technique and augmented with X-ray methods.
Electroplating Of Chromium Upon A Nickel Plated Magnesium Alloy, Harmel Dawson
Electroplating Of Chromium Upon A Nickel Plated Magnesium Alloy, Harmel Dawson
Bachelors Theses and Reports, 1928 - 1970
A nickel plating operation for magnesium alloys was investigated and proved successful in plating a small sample of a typical commercial magnesium alloy, Dowmetal J1.
Electrolytic Deposition Of Iron, Irving M. Kenoffel
Electrolytic Deposition Of Iron, Irving M. Kenoffel
Bachelors Theses and Reports, 1928 - 1970
In this thesis the purpose was to obtain a good iron deposit from a relatively simple bath. The deposit was to be of good nature and low in Carbon content. Also included is a summary of the uses to which electrolytic iron can be put as well as a summary of work done by other researchers in depositing iron electrolytically.
Electrical Resistivity Measurements Of Powder Metal Compacts, John M. Fitzpatrick
Electrical Resistivity Measurements Of Powder Metal Compacts, John M. Fitzpatrick
Bachelors Theses and Reports, 1928 - 1970
This work, as it was originally planned, was the arranging of an apparatus whereby electrical resistivity measurements could be made on powder compacts. It was also to include measurements on a series of copper-nickel compacts both before and after sintering.
The Effects Of Some Percentages Of Nickel On The Annealing Of Cartridge Brass, A. Edward Zezula
The Effects Of Some Percentages Of Nickel On The Annealing Of Cartridge Brass, A. Edward Zezula
Bachelors Theses and Reports, 1928 - 1970
The most important element in the alloying of steels, has also been used quite extensively as a third constituent in copper-zinc alloys. The chief characteristics of nickel which make it desirable as an alloying element are its toughness, high strength, and resistance to corrosion.
Some Preliminary Investiagtions Of The Magnetic Permeabilities Of Alloys Of The Ferromagnetic Metals, John H. Gambill Jr.
Some Preliminary Investiagtions Of The Magnetic Permeabilities Of Alloys Of The Ferromagnetic Metals, John H. Gambill Jr.
Bachelors Theses and Reports, 1928 - 1970
The problem presented for this thesis was an investigation of the magnetic properties of the alloys produced by the methods of powder metallurgy. The question behind this was the correlation of the magnetic properties with the bonding properties and with the diffusion of the constituents.
Powder Metallurgy, Cecil R. Waldron
Powder Metallurgy, Cecil R. Waldron
Bachelors Theses and Reports, 1928 - 1970
The metal powders may be produced in a number of different ways. In metals where the intercrystalline material is brittle enough, they may be ground in a ball mill or eddy mill. The fineness of such a powder is more or less controlled by the grain size of the original metal.

The Electrolytic Deposition Of Chromium Upon Aluminum, E. Fults, L. D. Voerge
Bachelors Theses and Reports, 1928 - 1970
The purpose or this investigation is primarily to determine the best conditions for plating chromium on aluminum. The work was carried out with the hope of obtaining coherent deposits, and of determining the conditions under which such deposits may be duplicated.
