        Bojjawar, Girish
        The future upcoming technologies in aerospace, transport and nuclear industries demand materials with superior mechanical properties that are also economically viable. The quest to achieve theoretical strength of material ...
      • Grain Boundary Processes In High Temperature Densification And Deformation Of Nanocrystalline Zirconia 

        Ghosh, Santonu (2011-02-08)
        Grain boundary processes play a major role in controlling different rate processes in yttria stabilized tetragonal zirconia. The present study concentrated on rate processes in tetragonal zirconia, which were significantly ...
      • Interfacial Processes in Densification of Cubic Zirconia 

        Maya Kini, K (2018-02-21)
        Sintering, a process of forming dense solid bodies from powder compacts remains the most important route for processing of ceramics. The process of sintering involves formation and growth of necks during initial stage, ...
      • An Investigation Of The Densification And Sinterforging Characteristics Of Alumina-Yttria Composites 

        Krishnamurthy, Saki (2012-11-19)
      • Length Scale Effects in Deformation of Polycrystalline Nickel 

        Ghosh, Pradipta (2017-09-20)
        The demand for compact, efficient and high performance electronic devices and sensor systems has become one of the primary driving force for rapid advancement in miniaturization of current technology. However, the attempt ...
      • Microstructure and texture evolution in wire drawing and its role on the tension and torsion response of nickel microwires 

        Arya, Abhinav
        It is now well known that the strength of the metallic materials depends on microstructural features such as dislocation density, grain size, and precipitates. The migration of lattice defects such as dislocations is a ...
      • On the creep behaviour of Ni based solid solution alloys from binary to quaternary 

        Bandla, Divya Sri
        On the creep behavior of Ni based solid solution alloys from binary to quaternary A power-law relationship between the steady state strain rate (𝜀̇) and imposed stress (σ) is well established so that the 𝜀̇∝𝜎^𝑛, at a ...
      • 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 ...
      • The role of polymer phase on rigidity percolation of ABS−spherical nickel microparticles composites 

        Bapari, Sambit
        Percolation and rigidity transitions are very important phenomena in random heterogeneous microstructures, as various physical properties change abruptly at some critical volume fractions of one phase. The concepts of ...
      • Superplastic Deformation Behaviour Of AZ31 Magnesium Alloy 

        Panicker, Radhakrishna M R (2009-05-29)
        Superplastic deformation behaviour of AZ31 magnesium alloy having initial grain sizes 8, 11 and 17μm alloy was investigated at 673 K with initial strain rates ranging from 1x10-2 to 1x10-4 s-1. Mechanical data on fine ...
      • Synthesis, Microstructural Stability and High Temperature Deformation of Alumina-Carbon Nanotube Composites 

        Gopalan, Hariprasad
        Structural ceramics such as alumina are known to have excellent hardness and high temperature mechanical properties. In view of this, they are used as refractory linings to mitigate the effect of high temperature exposure. ...
      • Understanding deformation mechanisms in the Hall-Petch breakdown regime of Ni-W alloys 

        Pandey, Keerti
        The substantially higher strengths of nanocrystalline metals has been to attributed to the well-known Hall-Petch relationship σ= σ_o+k_HP d^(-1/2) where 𝜎 is the yield stress, 𝜎𝑜 is the lattice friction stress, 𝑑 is ...
