Cold Model Study Of Formation And Breaking Of Raceway
(Indian Institute of Science, 2005-12-22)The raceway in the ironmaking blast furnace is a void in front of the hot blast tuyeres where coke and supplementary fuel burn to supply heat to the ironmaking process. The air velocity through the tuyeres is high (around ... -
Mean Field Study Of Point Defects In B2-NiAl
(Indian Institute of Science, 2005-12-22)Point defects control many properties of technological importance in intermetallic compounds such as atomic diffusion, creep, hardness, mechanical properties and sintering. Farther, since intermetallic compounds are ... -
Metastable Phases In Mg-Based Alloys
(Indian Institute of Science, 2005-12-22)Mg-based alloys form a variety of interesting structures including stable and metastable crystalline, stable and metastable quasicrystalline, nanocrystalline and amorphous phases. Many of these phases can be made to coexist ... -
Processing And Characterisation Of Bulk Al2 O3 p /AIN-Al Composites By Pressureless Infiltration
(Indian Institute of Science, 2005-12-22)Al-Mg alloys were infiltrated into porous alumina preforms at temperatures greater than 950°C where significant amount of nitride forms in the matrix. The present work aims to obtain a process window for growing A1N rich ... -
Processing And Characterization Of B4C Particle Reinforced Al-5%Mg Alloy Matrix Composites
(Indian Institute of Science, 2005-12-22)Metal matrix composites (MMCs) are emerging as advanced engineering materials for application in aerospace, defence, automotive and consumer industries (sports goods etc.). In MMCs, a metallic base material is reinforced ... -
Processing And High Temperature Deformation Of Pure And Magnesia Doped Alumina
(Indian Institute of Science, 2005-12-22)Creep resistance is an important design criterion at high temperatures especially when continuous attempts are made to increase the efficiencies by increasing the operating temperatures. Alumina is an important high ... -
Processing, Characterization And Evaluation Of A Functionally Graded Ai - 4.6% Cu Alloy
(Indian Institute of Science, 2005-12-22)In some applications the stress across the entire cross-section of a component is not uniform but varies with position. For example, maximum shear stress is highest at the inner surface of a thick-walled cylinder subjected ... -
Studies On Bio-Oxidation A Refractory Gold Containing Sulphidic Concentrate With Respect To Optimization And Modeling
(Indian Institute of Science, 2005-12-22)Although bacterial leaching of sulphidic minerals is a well-known phenomenon, it is only in the last ten years that full-scale bacterial leaching plants have been commissioned for gold processing. In order for bacterial ... -
Studies On Biodegradation Of Organic Flotation Collectors Using Bacillus polymyxa
(Indian Institute of Science, 2005-12-22)Numerous organic reagents of diverse structural composition are employed in the froth flotation process for the beneficiation of non-metallic and sulphide ores. Alkyl xanthates are used as collectors for sulphide ores while ... -
Studies On Corrosion Of Some Structural Materials In Deep Sea Environment
(Indian Institute of Science, 2005-12-22)Efficient exploitation and conservation of the oceans poses great technological challenges for scientists and engineers who must develop materials, structures and equipment for use in harsh environment of the oceans. For ... -
Study Of Friction And Wear Behaviour Of Nano-Embedded Aluminium Alloys
(Indian Institute of Science, 2005-12-22)In general, the bearing alloys have two types of microstructure i.e., either a soft matrix with discrete hard particles or a continuous matrix of the harder metal with small amount of the softer metal finely dispersed in ... -
Symmetry-Breaking Transitions In Equilibrium Shapes Of Coherent Precipitates
(Indian Institute of Science, 2005-12-22)We present a general approach for determining the equilibrium shape of isolated, coherent, misfitting particles by minimizing the sum of elastic and interfacial energies using a synthesis of finite element and optimization ...
