Characterisation, Consolidation and Mechanical Properties of TiAl Alloy Produced Using Titanox Powders
(The University of Waikato, 2007)Characterization of the three different as- received TiAl powders, namely Tax1, Tax2 and Tax3 produced by Titanox development Ltd has been done. Predominate TiAl phase was observed in all the three compositions .The powder ... -
Consolidation of Al-TiO₂ and Ti₃Al-Ai₂O₃ composite powders
(The University of Waikato, 2005)Pressureless sintering, hot pressing and sinter-HIP of Ti₃Al-Al₂O₃ and Al-TiO₂ composite powders have been carried out under inert atmospheres. The Al-TiO₂ composite powders were produced by discus milling Al/TiO₂ powder ... -
The Effect of Grain Refinement on the Castability of Magnesium-Aluminium Alloys
(The University of Waikato, 2007)Rapidly increasing fuel prices and global pressures to reduce the harmful effects of vehicle emissions are forcing vehicle manufacturers to look at alternative materials to reduce the mass of the vehicles they produce. ... -
Effects of high energy mechanical milling on the kinetics of solid state reactions
(The University of Waikato, 2000)The effects of high energy mechanical milling on the kinetics of solid state reactions in two binary metallic systems, Al-Ni and Cu-Al, and two metal-oxide systems, Al-TiO₂ and Cu(Al)-CuO, have been investigated by using ... -
Fabrication and characterization of micro-tubular solid oxide fuel cells
(The University of Waikato, 2004)Solid oxide fuel cells (SOFC) are an energy efficient, low pollution technology for generating power and have the potential to revolutionize energy generation. Tubular and planar concepts are the most common SOFC systems. ... -
Microstructure, Thermal Stability and Consolidation of Nanostructured and Ultrafine Structured Cu based Metal Matrix Composite and Alloy Powders Produced by High Energy Mechanical Milling
(The University of Waikato, 2010)Ultrafine grained and/or nanostructured Cu and Cu-(2.5-10)vol.%Al2O3 composite balls/granules/powder particles were produced using two high energy mechanical milling (HEMM) routes respectively. The microstructural evolution ... -
Modeling and simulation of the dynamic process in high energy ball milling of metal powders
(The University of Waikato, 2000)Mechanical alloying/mechanical grounding by using high-energy ball milling has been considered as a promising materials processing technique to synthesize materials. In this study, modeling simulation has been carried out ... -
Processing, microstructure and mechanical properties of TiₓAlᵧ/Al₂O₃ and Al₂Ti₄C₂/TiₓAlᵧ/Al₂O₃/TiC composites
(The University of Waikato, 2002)The TiₓAlᵧ/Al₂O₃ metal-ceramic composites materials [TiₓAlᵧ is α-Ti(Al,O), Ti₃Al, or TiAl] and Al₂Ti₄C₂/TiₓAlᵧ/Al₂O₃/TiC ceramic-ceramic composites with different volume fractions of ceramic reinforcement phases were ... -
Recovery and Purification of Titanium Dioxide and Aluminium Compounds from Corundum By-product of the TiPro Process
(University of Waikato, 2013)The TiPro process developed at the University of Waikato utilises an aluminothermic reaction to create titanium rich intermetallic alloys or alloy powders by solid-liquid separation. The product is then reduced with calcium ... -
Simulation of Titanium and Titanium Alloy Powder Compact Forging
(The University of Waikato, 2011)Simulation can be divided into two types: physical simulation and interactive numerical simulation. Physical simulation depends on testing smaller or cheaper samples rather than real objects to simplify models; Interactive ... -
Studies of modified pumice and titanomagnetite filtration media
(The University of Waikato, 2001)There is a continuing interest in filtration technologies capable of more efficient filtration, particularly of small microbial particles, but which place less reliance on the use of water treatment chemicals. In order to ... -
Study of Titanium based Composite Coatings for Resistance against Molten Aluminium Soldering on H13 Tool Steel
(University of Waikato, 2011)The service life of industrial components is limited predominantly by chemical corrosion, mechanical failure or mechanical wear. In the aluminium high pressure die casting industry, liquid aluminium is extremely reactive ... -
Synthesis, microstructure and mechanical properties of bulk ultrafine grained Ti-47Al-2Cr (at%) alloy
