Influence of 3D Printing Parameters on ULTEM 9085 Mechanical Properties Using Explainable Machine Learning

open access: yesSPE Polymers, Volume 7, Issue 4, October 2026.
An explainable machine‐learning framework predicts complete stress–strain behavior and key mechanical properties of FFF‐printed ULTEM 9085 from four printing parameters. Extra Trees delivered the most accurate and stable predictions, while SHAP and LIME clarified how each parameter influences material performance.

Microstructural and Fractographic Characterization of a Thermally Embrittled Nuclear Grade Steel: Part I - Annealing

open access: yesMaterials Research, 2002
A nuclear reactor pressure vessel steel was submitted to different annealing heat treatments aimed at simulating neutron irradiation damage. The obtained microstructures were mechanically tested with subsequent metallographic and fractographic ...

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

open access: yesRare 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

AUTO-SHAPE ANALYSIS OF IMAGE TEXTURES IN FRACTOGRAPHY

open access: yesImage Analysis and Stereology, 2011
The aim of this study is to estimate the velocity of fatigue crack growth (crack growth rate - CGR) from the texture in SEM images of crack surfaces. A simple and quick method is based on fitting training images as a linear combination of several small ...

Microstructure, Defects, and Fatigue Response of High‐Strength Tool Steels

open access: yessteel research international, Volume 97, Issue 10, Page 5164-5176, October 2026.
The martensitic tool steel family is designed for use in various working environments where they are subjected to repeatedly high mechanical loads. Despite the continuous upgrade of material´s microstructures through compositional development or processing techniques, defects remain a critical factor for the tool performance by leading to fatigue ...

Fatigue life of high strength steel for cold forming

open access: yesMetalurgija, 2017
The article presents the results of fatigue tests carried out on STRENX-type high-strength cold forming steel. For high-cycle fatigue tests carried out using low cycle loading frequencies of around 30 Hz, a ROTOFLEX machine was used. For ultra high-cycle

Improving fatigue resistance of translucent 4Y‐PSZ zirconia through glass gradation

open access: yesEuropean Journal of Oral Sciences, Volume 134, Issue 5, October 2026.
Abstract To evaluate the effect of graded glass infiltration on the fatigue behavior and mechanical reliability of translucent 4Y‐PSZ zirconia before and after hydrothermal aging, disc‐shaped specimens were fabricated by uniaxial pressing and divided into control and glass‐graded groups (n = 36/group).

Fracture load and three‐dimensional internal void analysis of direct composites used to restore worn molars

open access: yesEuropean Journal of Oral Sciences, Volume 134, Issue 5, October 2026.
Abstract This study evaluated (1) the load‐bearing capacity of molars restored with direct occlusal veneers fabricated either from short‐fiber‐reinforced composite (SFRC) or particulate‐filled composite (PFC) and the presence of internal voids within the materials, and (2) effect of water storage on the fracture load and correlation between internal ...

Effects of Annealing Temperature on Microstructural Evolution and Mechanical Properties in Cold-Rolled High-Nitrogen Austenitic Steel

open access: yesMetals
High-nitrogen austenitic steel (HNS) cold-rolled with a reduction rate of 25% was subjected to an investigation of the effect of annealing temperature on microstructural evolution, tensile properties and the variation in fracture surface morphology.
