Pulsed Laser Ablation Deposition of Intermetallic Thin Films: A Study of Evolution of Metastable Phases and Ultra-fine Microstructures
(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 ... -
Studies On Bulk And Multilayer Composites Of Nb-Si Alloys
(2013-08-02)The present thesis deals with Nb-Si alloy composites in both bulk and multilayer forms. The work has been divided into two parts. First part (chapter 4-6) deals with Nb based silicides binary and ternary alloys with ... -
Studies On Dissimilar Metal Welding
(2010-07-23)The area of research dealing with joining of dissimilar metals has been active in recent time. Although fusion and non-fusion techniques of joining have been effectively used for manufacturing components, a comprehensive ... -
Studies On Synthesizing Fe And Fe-Cu Nanopowders By Levitational Gas Condensation Process And Their Consolidation Characteristics
(2015-02-25)There exist large number of techniques for the preparation of nanostructured materials. Among them the preparation of nanopowders by gas/vapour condensation is a popular one. Because of very high level of surface to volume ... -
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 ... -
