Phase-field modeling of equilibrium shapes of precipitate and growth instabilities in the presence of coherency stresses
Precipitation-hardened alloys are one of the most technologically significant materials that are used for structural applications, where an important mode of strengthening is due to the impediment to the movement of ... -
A Physico-Chemical Approach in Binary Solid-State Interdiffusion
(2018-07-28)A physico-chemical approach (theory of dissociation and reaction) is developed, which can be used in binary diffusion couple to determine diffusion parameters of the product phases with wide homogeneity range, as well as ... -
Planar Fault Energies in L12 Compounds
High temperature metallic structural materials, such as Ni-base superalloys owe their strength to a two-phase microstructure consisting of an fcc matrix strengthened by intermetallic A3B type precipitates. The performance ... -
Plastic Deformation During Indentation Of Crystalline And Amorphous Materials
(2013-06-10)Indentation hardness, H, has been widely used to characterize the mechanical properties of materials for more than a century because of the following advantages of this technique; (1) it requires small sample and (2) the ... -
Polymer-based investigations into the surface chemistry of some sulphide minerals and the beneficiation of a low grade siliceous copper ore
Tanzania is endowed with rich mineral deposits containing gold, tanzanite, diamond, coal, uranium, iron ore, gemstones with low grade of the sulphide minerals namely chalcopyrite and pyrite. It is the third largest producer ... -
Polyvinylidene fluoride (PVDF) based Nanocomposites with Multi-layered Architecture Containing Core-shell Nanomaterials for Electromagnetic Interference Shielding
With the emergence of smart electronic devices, we have witnessed a rapid surge in the growth and subsequent drive-in for the miniaturization of electronic interfaces. Any electronic gadget that transmits, distributes, or ... -
Precipitate Growth and Coarsening in Ternary Alloys
(2018-08-20)We have studied precipitate growth and coarsening in ternary alloys using two different phase held models. The first one is a ternary extension of the classical Cahn-Hilliard (C-H) model in which both the phases are ... -

(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 Of Zirconia Based Honeycombs And Evaluation Of Thermo Mechanical Properties
(2010-08-16)Ceramic cellular solids, mainly honeycombs and foams, are a novel class of composite materials where one phase is an interconnected network of solid struts or plates and the other one an empty phase or possibly a fluid. ... -
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 ... -
