Comprehensive Investigation of the Mechanical Behavior of Nial-x (X=pt, Pd) Alloys: Effect of Composition, Orientation and Temperature
Gas turbine engines in the turbine section operate at temperatures exceeding 1300°C, which can cause high-temperature oxidation and reduce the lifespan of turbine blades. To counter this, thermal barrier coating (TBC) ... -
Synergistic Effect of Electromagnetic Forces on the Failure of Pre-Cracked Thin Metallic Conductors
Finite element method (FEM) simulations were performed, and distributions of current density, electromagnetic force, and stress fields due to the self induced electromagnetic forces were evaluated in a pre-cracked thin ... -
Studying the effect of Re on the Co-Ni-Al-Ti-Nb-Cr superalloy’s coarsening kinetics and establishing the high-throughput diffusion couple approach for alloy design
The studies are conducted to understand the effect of Re addition on microstructural evolution and coarsening kinetics of new Co-Ni-Al-Ti-Nb-Cr based superalloys. Lattice misfit is reduced by adding Re, confirmed from ... -
Microstructure – texture - mechanical property correlation in additively manufactured stainless Steel 316L and Cu-Ni-Sn
Metal additive manufacturing (AM) has gained considerable interest in recent years because of its ability of near net shape building of the components, one-go production, ability to make intricate designs and minimized ... -
The role of polymer phase on rigidity percolation of ABS−spherical nickel microparticles composites
Percolation and rigidity transitions are very important phenomena in random heterogeneous microstructures, as various physical properties change abruptly at some critical volume fractions of one phase. The concepts of ... -
Potential Applications of Snail Mucus in Cartilage Repair and Fabrication of Porous 3D Scaffolds
Articular cartilage damage is a major challenge in orthopedics. This medical condition is exacerbated by the cartilage's inability to self-repair due to the non-vascularization of the tissue and many other factors. Several ... -
Effect of High Pressure Torsion Processing on Precipitate Containing Alloys
Severe plastic deformation (SPD) processes yield excellent grain refinement in metallic materials by application of very large shear strains while retaining the initial sample dimensions. Its effects on simultaneously ... -
Solving The Unsolved In Multicomponent Diffusion: The Concept Of Constrained Diffusion Couple Methods
Quantitative diffusion analysis in multicomponent metallic systems has been a formidable task historically and despite decades of research, most of the diffusivity estimations were limited to interdiffusion and some intrinsic ... -
A Fundamental Investigation Of Discrete Liquid, Gas And Fines Flow In A Random Packed Bed Along With Applications
The discontinuous nature of liquid flow in a random packed bed is observed in many chemical engineering and metallurgical applications like blast furnace and heap leaching. So, to model the liquid flow in these systems, ... -
Silk-based Biomaterials for Wound Care and Tissue Regeneration
For most individuals, wound healing is a highly organized, straightforward process. However, there are instances where external intervention becomes necessary to support the body’s innate healing mechanism. In this thesis, ... -
On the creep behaviour of Ni based solid solution alloys from binary to quaternary
On the creep behavior of Ni based solid solution alloys from binary to quaternary A power-law relationship between the steady state strain rate (𝜀̇) and imposed stress (σ) is well established so that the 𝜀̇∝𝜎^𝑛, at a ... -
Structure-Property Correlation in Additively Manufactured High-Temperature Materials: Insights from Nickel-Based Superalloy IN718 & Nickel-Based Eutectic High Entropy Alloy AlCoCrFeNi2.1
High-temperature alloys are technically very important materials that possess higher resistance toward mechanical and chemical degradation at 0.4-0.6 TM for a constant/cyclic load. These attributes make them candidate ... -
A Multiscale Study of the Thermodynamics and Kinetics of Vacancy–grain-boundary Interactions
Grain boundaries (GBs) influence many physical and mechanical properties of crystalline materials. This is primarily because of their interactions with other kinds of defects, such as point and line defects. Such interactions ... -
