Investigation of Creep Properties of Ti‐43Al‐5V‐4Nb Alloy Considering Oxidation Effects Using Miniature Specimens

Fatigue &Fracture of Engineering Materials &Structures, EarlyView.
ABSTRACT In the present study, creep tests of a TiAl alloy were conducted using miniature specimens (d = 2 mm) under various conditions to investigate their creep properties at 760°C. The test results indicate that creep rupture time obtained using miniature specimens at identical applied stress levels increase with the order of test condition Ar gas ...

MXene‐Based Materials Contribute Better Alkali Metal–Chalcogen Batteries: Progress, Challenges, and Perspectives

Rare Metals, Volume 45, Issue 4, April 2026.
ABSTRACT Alkali metal–chalcogen batteries (AMCBs) are one of the most promising next‐generation energy storage systems because of their high energy density and reasonably low cost. However, the practical application of AMCBs is severely hindered by the volume expansion of the chalcogen cathode, the shuttle effect of polychalcogenides, and unstable ...

A Review on Cracking in Laser Additive Manufacturing of Nickel‐Based Superalloys: Types, Formation Mechanisms, and Suppression Strategies

Rare Metals, Volume 45, Issue 4, April 2026.
ABSTRACT Nickel‐based superalloys (Ni‐based superalloys) have attracted extensive attention in laser additive manufacturing (LAM) due to their capability to directly fabricate complex and high‐performance structural components. However, the rapid melting and solidification inherent to LAM result in intense thermal cycling, which induces high residual ...
