Insights Into High‐Temperature Mechanical Properties and Oxidation Behavior of Ta‐Optimized TiAl‐Based Alloys Additively Manufactured via Directed Energy Deposition

Rare Metals, Volume 45, Issue 6, June 2026.
ABSTRACT Directed energy deposition (DED) is an effective method to process complex components with high efficiency, owing to its significant advantage of material saving and features of microarea metallurgy and rapid solidification. This study presents a nano‐Ta‐optimized Ti‐45Al‐8Nb (at%)‐based alloy synthesized via DED. The prepared TiAl‐based alloy

Creep damage calculation along a semi-elliptical crack in a power plant component

, 2018
A 3D finite element model, based on the combination of a creep model and a ductility exhaustion approach, is presented and validated on the basis of creep crack growth tests.

Enhancing Corrosion Resistance and Mechanical Strength of 3D‐Printed Iron Polylactic Acid for Marine Applications via Laser Surface Texturing

Advanced Engineering Materials, Volume 28, Issue 9, 6 May 2026.
Laser surface texturing significantly improves the corrosion resistance and mechanical strength of 3D‐printed iron polylactic acid (Ir‐PLA) for marine applications. Optimal laser parameters reduce corrosion by 80% and enhance tensile strength by 25% and ductility by 15%.

Linear Low‐Density Polyethylene Clay Nanocomposites for Use in Type IV Liner Fabrication for Compressed Gaseous Storage

Engineering Reports, Volume 8, Issue 5, May 2026.
LLDPE–clay nanocomposites prepared without compatibilizer showed markedly improved clay dispersion after double‐pass extrusion, leading to over threefold increase in elastic modulus and a 45°C rise in thermal stability, highlighting their potential for Type IV hydrogen cylinder liner applications. ABSTRACT Compressed gaseous hydrogen storage represents

Creep crack growth in phosphorus alloyed oxygen free copper

, 2013
Creep crack growth (CCG) has been studied in phosphorus-alloyed oxygen-free copper (Cu-OFP) at 22, 75, 175, and 215 degrees C with compact tension (CT) specimens.

Applying a Multisector Scenario Framework to Evaluate Past and Future Public Surface Water Supply Infrastructure Strategies in Texas

Earth's Future, Volume 14, Issue 5, May 2026.
Abstract Facilitating decisions over future infrastructure transitions benefits from understanding past strategies to inform future scenario development. Here, we apply a scenario‐based indicator framework to generate plausible, spatially explicit future Public Water Supply Infrastructure (PWSI) alternatives.

Assessment of creep damage models in the prediction of high-temperature creep behaviour of Alloy 617

, 2019
This study aims to predict the creep response of Alloy 617 and assess the accuracy of three established creep damage models in predicting the creep time-to-failure (tf) and strain-to-failure (εf) in the temperature range of 800–1000 °C.

Assessment of modelling methodologies for prediction of high-temperature creep-fatigue behaviour of Alloy 617

, 2020
This study aims to assess the accuracy of various modelling methodologies in predicting creep-fatigue damage (dcf) and cycles-to-crack-initiation (Ni) of Alloy 617 at 850 °C and 950 °C.

Comparison of predicted cyclic creep damage from a multi-material weldment FEA model and the traditional r5 volume 2/3 weldment approach [PDF]

, 2018
The R5 assessment procedure for Integrity of High Temperature Structures employs a Weld Strain Enhancement Factor (WSEF) (dependent only upon classified weld type) for predicting creep fatigue crack initiation at weldments (V2/3 Appendix 4).
