Abstract Dynamic Strain Ageing (DSA) has reached widespread acceptance since its
proposal in the 1940's as the mechanism behind the Portevin-Le Chatelier effect in ferritic …

In this work, strength and microstructural evolution of superalloy Inconel 718 (IN718) are
characterized as a function of the initial microstructure created via direct metal laser melting …

Abstract The Portevin-Le Châtelier (PLC) effect is a plastic instability in alloys at certain
strain rates and deformation temperatures. This plastic instability exhibits serrated yielding in …

Inconel 625 is a nickel-based alloy that is mainly used in high-temperature applications.
Inconel 625 exhibits an unstable plastic flow at elevated temperatures characterized by …

Electrically-assisted manufacturing (EAM) is used for forming difficult-to-form materials such
as the Ni-based superalloy in recent years. Compared to the hot deformation, EAM is a more …

This work is concerned with determining the effect of powder reusing during fabrication of
Inconel 718 via laser powder bed fusion (LPBF) on tensile, compressive, and creep strength …

Selective laser melting (SLM) has unique advantages in manufacturing oxide dispersion
strengthened alloys due to its high cooling rate and tiny molten pool. In this study, the …

Although γ′ precipitates enhance the strength of Ni-based superalloys, they can also
promote an undesirable phenomenon called the Portevin–Le Chatelier (PLC) effect. Alloys …

The paper reviews the recent works concerning the Portevin–Le Chatelier (PLC) effect in
Advanced High-Strength Steels (AHSSs) with a special attention to high-strength medium …

Hydrogen embrittlement of Inconel 718 alloy was investigated. Multi-scale observation
technique were employed, comprising slow strain rate tensile tests, scanning electron …
