Effect of strain rate on ductile-to-brittle transition temperature of a free-standing Pt-aluminide bond coat

, 2011
The ductile-to-brittle transition temperature (DBTT) of a free-standing Pt-aluminide (PtAl) bondcoat was determined using the microtensile testing method and the effect of strain rate variation, in the range 10−5 to 10−1 s−1, on the DBTT studied.

Dynamic Control of Two‐Component Aggregation and Color‐Tunable Emission via Charge‐Transfer Coassembly

Aggregate, Volume 7, Issue 1, January 2026.
Charge‐transfer coassembly enables precise control over the dynamic aggregation process, resulting in morphology evolution from amorphous aggregates to rod‐like and needle‐like microcrystals, accompanied by a significant fluorescence enhancement. This strategy yields widely tunable solid‐state emission from green to orange‐red, unveiling fundamental ...

In Situ Tailoring of FCC Ductile Phases for High‐Strength Wear‐Resistant Crack‐Free W‐Based Metallic Coatings

Rare Metals, Volume 45, Issue 1, January 2026.
ABSTRACT Tungsten is inherently brittle and particularly prone to thermal stress concentration and crack formation during additive manufacturing processes such as laser cladding, which severely limits its engineering applications as a coating material. To address this issue, this study proposes an in situ toughening strategy involving the introduction ...
