Suppressed liquation and microcracking in linear friction welded WASPALOY

, 2012
Fusion welding of nickel-base superalloys is often associated with fusion zone solidification cracking and/or liquation induced heat affected zone (HAZ) cracking. As an alternative joining technology, linear friction welding (LFW) was used in the current

Temperature-dependent deformation mechanisms and quantitative strength analysis of a Ni-based superalloy with bimodal precipitation distribution

Journal of Materials Research and Technology
Ni-based superalloys are essential for high-temperature applications in aerospace, yet their mechanical properties are intricately linked to the size distribution of γ′ precipitations.

Recent Advances in Creep Modelling Using the θ Projection Method

Metals
The theta projection method has been used to predict uniaxial creep curve shapes for a wide range of materials. However, one of the criticisms of the existing method is that the multilinear approach, commonly used to correlate theta parameters to applied

An electrochemical study of hydrogen uptake and elimination by bare and gold-plated waspaloy

, 1984
Two electrochemical methods for the determination of hydrogen concentrations in metals are discussed and evaluated. The take-up of hydrogen at a pressure of 5000 psi by Waspaloy metal was determined experimentally at 24 C.

A state-variable model for the hot deformation of Waspaloy

, 2002
A semi-empirical history-dependent constitutive model for the high temperature deformation of Waspaloy is presented. Model equations have been formulated in terms of the evolution of state variables, in particular an internal back stress, directly ...
