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 ...
Microstructural Stability of Fully Lamellar and Duplex y-TiAl Alloys During Creep
(2018-03-06)
γ-TiAl based alloys have attracted considerable research interest in the past few decades and have gained niche high temperature applications in aero-engines and automobiles. As high temperature structural materials, these ...
Effect Of Free-Volume On The Fracture And Fatigue Of Amorphous Alloys
(2010-07-01)
Bulk metallic glasses (BMGs) are a new class of structural materials and exhibit unique combinations of mechanical properties. As a result, their mechanical behavior has been an active area of scientific pursuit in the ...
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 ...
Evolution of Microstructure and Texture during Severe Plastic Deformation of a Magnesium-Cerium Alloy
(2018-01-03)
Magnesium alloys have poor formability at room temperature, due to a limited number of slip systems owing to the hexagonal closed packed structure of magnesium. One possibility to increase the formability of magnesium ...
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. ...
