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 ...
Superplastic Deformation Behaviour Of AZ31 Magnesium Alloy
(2009-05-29)
Superplastic deformation behaviour of AZ31 magnesium alloy having initial grain sizes 8, 11 and 17μm alloy was investigated at 673 K with initial strain rates ranging from 1x10-2 to 1x10-4 s-1. Mechanical data on fine ...
Study Of Fracture Properties Of NiAl Bond Coats On Nickel Superalloy By Three Point Bending Of Microbeams
(2009-05-13)
The continuing quest for higher performance levels of modern gas turbine engines has been accompanied by the demand for higher engine operating temperatures. The use of Thermal Barrier Coatings (TBCs) enabled gas turbines ...
Processing And Characterisation Of Bulk Al2 O3 p /AIN-Al Composites By Pressureless Infiltration
(Indian Institute of Science, 2005-12-22)
Al-Mg alloys were infiltrated into porous alumina preforms at temperatures greater than 950°C where significant amount of nitride forms in the matrix. The present work aims to obtain a process window for growing A1N rich ...
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 ...
Modeling Of Liquid Flow In A Packed Bed Under Influence Of Gas Flow
(2009-03-05)
The aim of the current study is to model (non-wetting) liquid flow in a packed bed under the influence of gas flow. It has been observed experimentally that non-wetting liquid flows in a packed bed in form of small droplets ...
Microstructure And Texture Evolution And Its Effect On Mechanical Properties In Dilute Magnesium Based AZ21 Alloy
(2009-03-05)
Dilute Mg alloys are exclusively identified for wrought structural applications in automotive industry. Any improvement in mechanical properties of alloys is possible only by grain size refinement and by the development ...
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 ...
Mean Field Study Of Point Defects In B2-NiAl
(Indian Institute of Science, 2005-12-22)
Point defects control many properties of technological importance in intermetallic compounds such as atomic diffusion, creep, hardness, mechanical properties and sintering. Farther, since intermetallic compounds are ...
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. ...
