High Cycle Fatigue Properties of PM‐HIPed High‐Nitrogen Tool Steel: Effect of Surface Condition

open access: yesFatigue &Fracture of Engineering Materials &Structures, Volume 49, Issue 6, Page 2097-2115, June 2026.
ABSTRACT This study explores the impact of surface condition on high‐cycle fatigue performance of a high‐nitrogen martensitic tool steel manufactured through powder metallurgy and hot isostatic pressing. In near‐net manufacturing applications, acid‐leaching pickling treatment and/or machining is used as a post‐treatment to remove the powder container ...

Accelerated Fatigue Testing of High‐Speed Steel

open access: yesFatigue &Fracture of Engineering Materials &Structures, Volume 49, Issue 6, Page 2156-2166, June 2026.
ABSTRACT The staircase method is commonly employed in the characterization of metals to determine their fatigue limit. In this approach, the stress amplitude is systematically varied around the assumed fatigue limit in consecutive tests. However, its applicability for in‐process optimization in alloy design and development is limited by the large ...

AI‐Driven Properties Prediction in Si3N4 Ceramics: Image‐Based and Processing Parameter Strategies

open access: yesInternational Journal of Applied Ceramic Technology, Volume 23, Issue 3, June 2026.
ABSTRACT This review presents AI‐based approaches for predicting key properties of silicon nitride (Si3N4) ceramics from both microstructural images and process parameters. Convolutional neural networks (CNNs) successfully predicted bending strength, fracture toughness, and dielectric breakdown strength directly from microstructural images, with higher

Effect of Sintering Aid Composition and Porosity on the Oxyacetylene Torch Response of Silicon Nitride for RF Windows

open access: yesJournal of the American Ceramic Society, Volume 109, Issue 6, June 2026.
Silicon nitride samples were slip cast using yttrium oxide–aluminum oxide and ytterbium oxide sintering aids to fabricate plates with up to 40% porosity and compare them to a fully dense commercial standard. Silicon nitride plates were tested with an oxyacetylene torch to investigate changes in front and back face temperature, spectral emissivity ...

Grain Growth Kinetics and Polytype Transformation of SiC During the Intermediate Stage of Induction Heating Sintering

open access: yesJournal of the American Ceramic Society, Volume 109, Issue 6, June 2026.
ABSTRACT Grain growth kinetics and polytype transformation play a critical role in determining the final microstructure and properties of SiC ceramics, particularly during the intermediate stage of sintering when the microstructure evolves most significantly.
