    • Metastable Phases In Mg-Based Alloys 

      Subramaniam, Anandh (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 ...

    • Mean Field Study Of Point Defects In B2-NiAl 

      Gururajan, M P (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 ...

    • Cold Model Study Of Formation And Breaking Of Raceway 

      Sastry, Ghatty S S R K (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 ...

    • Processing And Characterization Of B4C Particle Reinforced Al-5%Mg Alloy Matrix Composites 

      Khan, Kirity Bhusan (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 Characterisation Of Bulk Al2 O3 p /AIN-Al Composites By Pressureless Infiltration 

      Swaminathan, S (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 High Temperature Deformation Of Pure And Magnesia Doped Alumina 

      Swaroop, N R Sathya (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 ...

    • Studies On Biodegradation Of Organic Flotation Collectors Using Bacillus polymyxa 

      Chockalingam, Evvie (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 ...

    • Processing, Characterization And Evaluation Of A Functionally Graded Ai - 4.6% Cu Alloy 

      Sivakumar, V (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 ...

    • Pulsed Laser Ablation Deposition of Intermetallic Thin Films: A Study of Evolution of Metastable Phases and Ultra-fine Microstructures 

      Bysakh, Sandip (Indian Institute of Science, 2005-07-27)
      This thesis is devoted to the deposition of intermetallic thin films by laser ablation deposition (LAD) and their characterization. Pulsed laser ablation and subsequent deposition of the ablated vapours produces films under ...

    • Bubble Solid Interaction 

      Mukherjee, Manas (Indian Institute of Science, 2005-03-09)
      The interaction of a bubble with solid surfaces, hydrophobic and hydrophilic, was investigated. When a bubble approaches towards a solid surface, a thin liquid film forms between them. The liquid in the film drains until ...

    • Structures, Thermodynamics and Phase Relations in Selected Oxide Systems 

      Lwin, Kay Thi (Indian Institute of Science, 2005-02-08)
      Understanding of the interrelationship between structure, thermodynamic properties and phase diagrams is very useful for rationalizing the behavior of materials and development of predictive models, which can be used to ...
