Precipitation in Powder-metallurgy, Nickel-base Superalloys: Review of Modeling Approach and Formulation of Engineering (postprint)

A Comparison of the Plastic-flow Response of a Powder-metallurgy Nickel-base Superalloy (postprint)

Study of Advanced Materials for Aircraft Jet Engines Using Quantitative Metallography

The aerospace industry is one of the biggest consumers of advanced materials because of its unique combination of mechanical and physical properties and chemical stability. Highly alloyed stainless steel, titanium alloys and nickel based superalloys are mostly used for aerospace applications. High alloyed stainless steel is used for the shafts of aero engine turbines, titanium alloys for compre...

Effect of bonding time on microstructure and mechanical properties during TLP bonding of nickel-base superalloys Hastelloy C276 and Stainless Steel AISI316

Joining of Hastelloy C276 nickel-base superalloy to AISI316 Stainless Steel using BNi-2 interlayer performed by transient liquid phase process (TLP) at 1150°C for 5 and 30 minutes. Bonding microstructure was studied using an Optical microscope and a scanning electron microscope (SEM). Vickers hardness test and shear strength test have been used to evaluate the mechanical properties. Microstruct...

Microstructural aspects of fatigue in Ni-base superalloys.

Nickel-base superalloys are primarily used as components in jet engines and land-based turbines. While compositionally complex, they are microstructurally simple, consisting of small (50-1000 nm diameter), ordered, coherent Ni(3)(Al,Ti)-type L1(2) or Ni(3)Nb-type DO(22) precipitates (called γ(') and γ(''), respectively) embedded in an FCC substitutional solid solution consisting primarily of Ni...
