Effect of Annealing Temperature on Microstructure and Dry‐Sliding Behavior of Powder Bed Fusion–Laser Beam Ti6Al2Sn4Zr6Mo Alloy

open access: yesAdvanced Engineering Materials, EarlyView.
Heat treatment parameters critically affect the wear resistance of powder bed fusion–laser beam (PBF‐LB)‐produced Ti–6Al–2Sn–4Zr–6Mo alloy. This study found that optimizing annealing temperature allows to obtain a tailored microstructure, which enhances the dry‐sliding behavior by forming a stable and functional mechanically mixed layer (MML), ensuring

A Novel Simplified Approach to Physically Simulate Wire‐Arc Directed Energy Deposition Conditions

open access: yesAdvanced Engineering Materials, EarlyView.
Scarcity of specialized titanium alloy wires and high experimental wire production costs impedes wire‐arc directed energy deposition (waDED) adoption in industry. A novel, wireless approach is introduced to accelerate and economize titanium alloy development.

3D‐Printable Near‐Infrared‐Responsive Microscale Cantilever made of the Composite Consisting of Ceramic Particles and Graphene Flakes

open access: yesAdvanced Engineering Materials, EarlyView.
A near infrared‐responsive microscale cantilever is developed using a 3D‐printable composite based on photocurable resin consisting of sepiolite and graphene flakes. The material absorbs 1064 nm light, causing shape transformation with an average displacement of 1.3 mm in 1.7 s. Displacement is measured via video recording.

Multimode Adaptive Thermoregulation Enabled by Shape Morphing and Radiative Cooling Porous Polyurethane

open access: yesAdvanced Engineering Materials, EarlyView.
A shape‐morphing, porous polyurethane film combines passive radiative cooling with folding to deliver multilevel heating‐and‐cooling control. High solar reflectance and midinfrared emissivity keep surfaces up to 3.5 °C cooler in direct sunlight, while photothermal triggering folds the film to absorb solar heat.

Heterostructure‐Specific Toughening Mechanisms in Metallic Laminates

open access: yesAdvanced Engineering Materials, EarlyView.
This study highlights how various aspects of the heterostructural design of metallic laminates can be specifically tailored to achieve improved fracture resistance for damage‐tolerant designs of cyclically stressed components. Based on results from in situ fatigue crack growth tests, a comprehensive overview of the formation and development of ...

Biotite effect on the anisotropic properties of gneiss in Eastern Himalayas, China

open access: yesJournal of Rock Mechanics and Geotechnical Engineering
Intact rocks with layered microstructures, such as gneiss, exhibit strong anisotropy. Although anisotropy in the macroscopic strength of gneiss has been widely reported, the role of microstructures in tensile mechanics remains largely unclear.

The effect of pollarding on tensile strength of Persian oak (Case Study: Dinarkooh, Ilam) [PDF]

open access: yesمجله جنگل ایران, 2016
Previous studies have shown that vegetation enhances the soil shear strength and the stability of slopes through soil reinforcing. The amount of reinforcement mainly depends on the density and tensile strength of the root. The objective of this study was
