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.

External and Internal Cracking Caused by Heat Treatment in Laser Powder Bed Fusion‐Fabricated Inconel 738LC Components

Advanced Engineering Materials, Volume 28, Issue 18, 23 September 2026.
Manufacturing problems such as heat treatment‐induced cracking hinder the widespread application of the laser powder bed fusion (LPBF) process to superalloys. In this study, cracks in the LPBF components of Inconel 738LC superalloy are characterized after heat treatment at various temperature ranges, revealing two distinct cracking behaviors.

Microstructure‐Controlled Crack Propagation and Fracture Resistance in MoSiBTiC Alloy Revealed by Multiscale Extended Finite Element Method Modeling

Advanced Engineering Materials, Volume 28, Issue 17, 9 September 2026.
A two‐dimensional multiscale finite element analysis framework was established for the first‐generation MoSiBTiC alloy, and the mechanical and fracture‐related parameters of the constituent phases were calibrated through experiments and simulations. The framework provides a basis for analyzing crack propagation behavior in its complex microstructure ...

Slip Localization Intensification Mediated by Grain Boundary Sliding in a Polycrystalline Nickel‐Based Superalloy

Advanced Engineering Materials, Volume 28, Issue 17, 9 September 2026.
The temperature dependence of fatigue behavior in nickel‐based superalloys is investigated through high‐resolution measurements of plastic localization. While increasing temperature reduces localization and enhances fatigue performance in René 88DT, Inconel 718 exhibits a sharp degradation at intermediate temperature due to intensified slip ...
