11. Microstructure Evolution and Mechanical Properties of Haynes 282
Abstract : Precipitation-hardened nickel-based superalloys find wide applications in aero engines and land-based gas turbines due to a combination of properties such as high temperature strength, resistance to oxidation and corrosion, fabricability, and creep strength. Structural engine components are traditionally cast to achieve higher degree of geometrical design freedom. READ MORE

12. On the Effect of Grain Size and Hardness on the Machinability of Superalloys and Chip Deformation
Abstract : Superalloys are used in applications such as gas turbines, steam power plants and nuclear power systems that require good high temperature properties and/or exceptional corrosion resistance. Superalloys are classified as materials that are “difficult to machine”. In production machining is a most commonly occurring procedure. READ MORE

13. Investigating the effect of extending powder particle size distribution of Ti-6Al-4V produced by powder bed fusion laser beam process : Influence of process parameters on material integrity
Abstract : This thesis focuses on the topic of PBF-LB applied to titanium alloys. Of allalloys, an α + β is chosen, named Ti-6Al-4V. The selection of this particular alloy is driven by its current widespread use in many industrial applications where high strength coupled with low density are both desirable properties. READ MORE

14. Effects on Machinability due to Microstructure Variations in Case Hardening Steel
Abstract : Typical products made of case hardening steel are transmission parts like gear wheels, pinions and crown wheels. Case hardening produces a carbon-rich surface and provides the parts with both enhanced hardness and fatigue life. READ MORE

15. Shape Control Synthesis and Microstructure Studies of Metal Nanoparticles
Abstract : Metal nanoparticles have been extensively studied in recent years due to their unique chemical, biological and physical properties. Gold (Au) and palladium (Pd) nanoparticles are two of the most popular materials because Au nanoparticles have a strong localized surface plasmon resonance effect and Pd nanoparticles have high hydrogen adsorption and chemical catalytic capacities.
