In this thesis, un-u3si2 nuclear fuel was fabricated using spark plasma sintering and characterized to analyze the microstructure and crystal struc- ture of the resulting pellets this work was done in collaboration with accident tolerant fuel research, an effort which aims at developing nuclear fuel with superior safety and. A thesis submitted in fulfilment of the requirements for the degree of doctor of philosophy khurram award the content of the thesis is the result of work which has been carried out since the official commencement date consolidated via vacuum sintering and spark plasma sintering (sps) compared to. Spark plasma sintering (sps) is a rapidly developing method for densification of powders into compacts it belongs to the so-called “field assisted sintering techniques” that enable rapid sintering at much lower temperatures than the classical approaches of pressureless sintering of green pellets or hot isostatic pressing. 24 mechanisms during densi cation by spark plasma sintering 14 25 state of the 31 thermal-electrical coupling scheme during spark plasma sintering process 40 32 comparison of the work of this thesis is a part of the iris project: innovative manufacturing route for intermetallic alloys. Spark plasma sintering is a method of consolidating nanostructured powder materials and also composites and gradient materials in the presence of an electromagnetic field, by means of low-voltage sources of powerful current the main benefit of spark plasma sintering is that previously impossible.
In this thesis, studies on the processing of cerium dioxide and its composites using a novel sintering technique called spark plasma sintering (sps) were carried out the effect of sps process parameters on the physical and chemical changes of cerium dioxide were investigated the results indicate that. And hotpressing/spark plasma sintering sections, and finally a conclusions chapter which finishes with recommended future work this format will suit this thesis best as the processing methods and their tests can be described separately 11 ceramic composites ceramic composites specifically those containing alumina. Activation energies of spark plasma sintered oxide dispersion strengthened steels by derek andrews a senior thesis submitted to the faculty of brigham young university - idaho in partial fulfillment of the requirements for the degree of bachelor of science department of physics brigham young.

Of sic nanoparticles and consolidated through spark plasma sintering the effect of processing parameters on the densification, microstructure, and properties of the processed master thesis, king fahd university of petroleum and minerals , dhahran, saudi arabia, 2012 25 al-aqeeli, n abdullahi, k.
Numbers of papers have described the various physicochemical phenomena during spark plasma sintering process [10,11,18-29] the detail was summarized in the literature  because of an absence of the direct evidence about spark discharge in the spark plasma sintering process, some publications also called it as. London for his technical support on the spark plasma sintering furnace without his support, most of the work in this thesis could not possibly have been carried out i owe my sincere thanks to dr mike keeble at the buehler ltd for this kind help with the hardness tests i would also like to thank my friend, weichen xu for his. Microstructural evolution of nickel during spark plasma sintering by matthew thomas luke a thesis submitted in partial fulfillment of the requirements of the degree of master of science in materials science and engineering boise state university may 2010.
Sps facility at iit kanpur is procured with partial funding from department of science and technology government of india as well as care funding from iit kanpur all the users, while publishing the sps results in a research paper / technical report / phd thesis, must therefore take the responsibility in putting the following. This study demonstrates the efficiency of the spark plasma sintering (sps) as a suitable technique to elaborate a dense polymer polytetrafluoroethylene (ptfe) which is difficult to sinter by conventional sintering methods eg hot pressing or hot iso-static pressing indeed, sps is a very powerful technique not only to densify.
