Ultrasonic Vibration Assisted Laser Processing: A Hybrid Paradigm for Extreme Surface Enhancement

Rare Metals, Volume 45, Issue 10, October 2026.
ABSTRACT Traditional laser processing techniques offer many advantages, but they often encounter limitations such as heat‐affected zones, recast layers, residual tensile stresses, and poor surface finish. The integration of ultrasonic vibration (UV) presents a promising hybrid approach to overcome these challenges by introducing beneficial effects like

Tuning Grain Boundary Carbides via Solute Rare‐Earth Elements to Prevent Intergranular Brittle Fracture

Rare Metals, Volume 45, Issue 10, October 2026.
ABSTRACT Carbides strengthen the grain boundaries; nevertheless, excessive carbide precipitates embrittle the grain boundaries of high‐temperature alloys during prolonged service. Here, we provide direct evidence of solute rare‐earth atoms and demonstrate that they can trap vacancies and inhibit interstitial diffusion, restraining carbide precipitation

A Kinetic Model for Oxide–Carbonitride Inclusion Heterogeneous Nucleation and Precipitation during Superalloy Solidification

Metals
Complex oxide–carbonitrides (MgO-Ti(CN), Al2O3-Ti(CN), and MgO·Al2O3-Ti(CN)) are the most common non-metallic inclusions presented in cast and wrought superalloys.

Nonequilibrium Precipitation Pathway Enabling Direct δ‐phase Formation and Enhanced Cryogenic Strength–Ductility in an Additively Manufactured Multi‐Principal‐Element Alloy

Rare Metals, Volume 45, Issue 10, October 2026.
ABSTRACT Overcoming the strength–ductility trade‐off in face‐centered cubic (FCC) multi‐principal element alloys (MPEAs), particularly at cryogenic temperatures, remains a significant challenge. Here, a laser powder bed fusion (LPBF)–enabled direct aging strategy is employed to modify the precipitation behavior in a Ni53Fe20Cr23Nb4 (at%) alloy.

Tailoring the Mechanical Properties of L‐DED‐Fabricated γ‐TiAl Alloys Through Heat Treatment: Correlating Microstructural Evolution With Fracture Mechanisms

Rare Metals, Volume 45, Issue 10, October 2026.
ABSTRACT Laser‐directed energy deposition (L‐DED) offers a flexible route for fabricating γ‐TiAl components, but the as‐deposited microstructure requires post‐processing to overcome limited deformation capability. Here, an L‐DED Ti–48Al–2Cr–2Nb alloy was subjected to solution and solution‐aging treatments.

Enhancing microstructural fidelity in near‐field high‐energy diffraction microscopy reconstruction with Noise2Void denoising

Journal of Applied Crystallography, Volume 59, Issue 5, Page 1531-1543, October 2026.
A self‐supervised deep learning model, Noise2Void (N2V), denoises near‐field high‐energy diffraction microscopy diffraction images without requiring unobtainable clean data. These images allow for lower segmentation thresholds and detection of smaller and weaker diffraction peaks, which are often discarded or overlooked with conventional image ...

Polymeric Steric Entrapment Synthesis of Compositionally Complex Rare‐Earth Aluminum Garnets (CCREAGs)

Journal of the American Ceramic Society, Volume 109, Issue 10, October 2026.
ABSTRACT This work focuses on the polymeric steric entrapment (PSE) technique to synthesize a series of (nRE1/n)3Al5O12, or compositionally complex rare‐earth aluminum garnet (CCREAG) compositions, where RE represents a variety of rare‐earth cations and n is the number of cations occupying the shared position. Using PSE, CCREAGs crystallized at ∼900°C.
