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 ...
Development Of Cast Magnesium Alloys With Improved Strength
(2014-05-15)
Aim of the present work was to explore the possibility of improving strength of cast Mg by alloying additions, viz., Si and Zn+Al. All the alloys were produced by squeeze casting technique using squeeze pressure of 12MPa ...
A Study Of Crystallographic Texture, Residual Stresses And Mechanical Property Anisotropy In Aluminium Alloys For Space Applications
(2013-05-21)
Aluminium alloys, which are the most widely used materials in the aircraft and aerospace industries, find their applications due to high strength–to-density ratio, resistance to catastrophic fracture, high degree of ...
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 ...
Bubble Solid Interaction
(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 ...
Study Of Solidification And Microstructure Produced By Cooling Slope Method
(2016-05-05)
In most casting applications, dendritic microstructure morphology is not desired because it leads to poor mechanical properties. Forced convection causing sufficient shearing in the mushy zone of the partially solidified ...
Multi-Phase Modeling Of Microporosity And Microstructures During Solidification Of Aluminum Alloys
(2014-04-23)
Manufacturing of light-weight materials is associated with several types of casting defects during solidification. Porosity defects are common, especially in aluminum and its alloys, which initiate crack propagation and ...
Single-Phase And Multi-Phase Convection During Solidification Of Non-eutectic Binary Solutions
(2014-10-20)
During solidification of non-eutectic alloys, non-isothermal phase change causes dendritic growth of solid front with liquid phase entrapped within the dendritic network producing the mushy region. Solidification causes ...
Microstructure Evolution In Semisolid Processing
(2014-09-09)
In this thesis, we present an experimental and numerical study of globularization during reheating of thixocast billet having non-dendritic microstructure. The process of reheating is an important step in the semisolid ...
