Residual Stresses in Ultrasonically Peened Fillet Welded Joints

Advanced Materials Research, 2014
Fatigue cracks mostly initiate at areas subjected to high tensile residual stress and stress concentration. Ultrasonic peening is a mechanical method to increase fatigue life by imparting compressive residual stress. In this study residual stresses are characterized in fillet welded ship structural steel plates with longitudinal attachments. As-welded,

Microstructural and Mechanical Properties of a Hard Anodic Coating Applied on an Elastically Prestrained Aluminum Substrate

Advanced Engineering Materials, Volume 27, Issue 15, August 2025.
Prestraining the substrate influences coating formation process. Higher prestraining force leads to higher coating thickness and lower hardness. Increase in prestraining force enhances preliminary damage in hard anodic coating. Fatigue damage mechanisms change for hard anodized prestrained samples.

Determining the Necessity of Post‐Processing Heat Treatment for the 316L Stainless Steel Manufactured by Laser Powder Bed Fusion through Evaluation of Mechanical and Corrosion Properties

Advanced Engineering Materials, Volume 27, Issue 9, May 2025.
This article examines the effect of postprocessing heat treatment on 316L stainless steel (SS316L) produced via laser powder bed fusion (LPBF). Heat treatment slightly affects property anisotropy, reduces strength, and enhances elongation. However, it increases corrosion susceptibility due to nanoscale precipitations, though overall corrosion ...

Precision Strain Engineering in Perovskite Optoelectronics via Shock‐Driven Gradient Annealing for Enhanced Stability and Light Response

Small, Volume 21, Issue 20, May 19, 2025.
Residual tensile strain in perovskite films elevates defect density and impedes charge extraction. Laser shock‐driven gradient annealing (SDGA) leverages plasma shocks to release strain and refine crystallization, yielding uniform, low‐defect films.
