Pelletizing/reslurrying as a means of distributing and firing clean coal

Description: Battelle-Columbus and Amax Research Development conducted a program to develop a process to transport, handle, store, and utilize ultra-fine, ultra-clean (UFUC) coals. The primary objective was to devise a cost-effective method, based on conventional pelletization techniques, to transform the sludge-like filter cake produced in advanced flotation cleaning processes into a product which could be used like lump coal. A secondary objective was the production of a pellet which could be readily conv… more

Powder Metallurgy of Uranium Alloy Fuels for TRU-Burning Reactors Final Technical Report

Description: Overview Fast reactors were evaluated to enable the transmutation of transuranic isotopes generated by nuclear energy systems. The motivation for this was that TRU isotopes have high radiotoxicity and relatively long half-lives, making them unattractive for disposal in a long-term geologic repository. Fast reactors provide an efficient means to utilize the energy content of the TRUs while destroying them. An enabling technology that requires research and development is the fabrication metallic … more

Effect of Extrusion Temperature on the Microstructural Development of Powder Metallurgy Ti-47A1-2Cr-1Nb-1Ta Alloy

Description: Effect of extrusion temperatures on the microstructural development of a powder metallurgy (PM) Ti-47Al-2Cr-1Nb-1Ta (at. %) alloy has been investigated. Microstructure of the PM alloy extruded at 1150 C consists of a fine-grained ({gamma} + {alpha}{sub 2}) two-phase structure in association with coarse grains of metastable B2 (ordered bcc) phase. In addition, fine {omega} (ordered hexagonal) particles are also found within some B2 grains. The PM alloy containing the metastable B2 grains display… more

Microstructural Evolution in the 2219 Aluminum Alloy During Severe Plastic Deformation

Description: Numerous investigations have demonstrated that intense plastic deformation is an attractive procedure for producing an ultrafine grain size in metallic materials. Torsional deformation under high pressure and equal-channel angular extrusion are two techniques that can produce microstructures with grain sizes in the submicrometer and nanometer range. Materials with these microstructures have many attractive properties. The microstructures formed by these two processing techniques are essentially… more

PREPARATION AND EVALUATION OF ALUMINUM-35 w/o URANIUM ALLOYS CONTAINING UP TO 3 w/o TIN OR ZIRCONIUM

Description: The effects of ternary additions of up to 3 wt.% Sn or Zr to an Al-35 wt.% U extrusion alloy were evaluated on the basis of casting characteristics, UAl/sub 3/ retention, extrusion behavior, mechanical properties, and corrosion resistance. Both additions increased the fluidity of the alloy, and both promoted retention of UAl/sub 3/. The best fluidity was obtained by a 2 wt.% Sn addition, while Zr was the more effective stabilizer of UAl/sub 3/. The retention of UAl/sub 3/ decreased the extrusio… more
