Nickel-based superalloys are currently the material of choice for use in high-temperature
applications due to their excellent high-temperature strength. It is understood that many …

In this work, a multi-scale approach was applied to reveal the evolution mechanisms of the δ
(Ni 3 Nb) phase and the resultant mechanical responses in wire-arc additive manufactured …

A new model for the yield stress in superalloys accounting for unimodal and multimodal γ′
size distributions is presented. A critique of the classic models on γ′ shearing is presented …

The ultrafine-grained microstructures, mechanical properties and electrical conductivity of a
Cu–0.87% Cr–0.06% Zr alloy subjected to multiple equal channel angular pressing (ECAP) …

The effect of heat treatment on the microstructure and mechanical properties of Ni-base
superalloy Haynes 282 was investigated. Applying a standard two-step ageing (1010° C/2 …

Ni-based wrought superalloys are a type of superalloy produced through casting-forging
processes, and usually their high-temperature performance is strongly influenced by …

Post-heat treatment is a necessary and important step for additive-manufactured products to
relieve residual stress and to further improve mechanical performance. In this work, the heat …

Alloy 718 is a Ni-based superalloy commonly used for parts of aircraft engines and power
plants where very high demands on high-temperature yield strength, creep and corrosion …

Abstract Models of the multiple strengthening mechanisms operating concurrently in nickel-
based superalloys have been combined to provide predictions of the overall yield strength …

The phase content and the strengthening of two copper alloys, 0.1 Cr–0.1 Zr and 0.9 Cr–0.1
Zr, subjected to aging treatments were studied. The size of second phase particles and the …
