Beneficiation Studies On Molybdenite Ore From Harur Area, Tamil Nadu
(2014-09-15)
Molybdenum is a versatile alloying and refractory metal of strategic importance. In India almost all molybdenite is obtained currently as st byproduct from copper and uranium deposits. The present Indian production is only ...
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 ...
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 ...
