Bistable Mechanisms 3D Printing for Mechanically Programmable Vibration Control

Advanced Engineering Materials, EarlyView.
This work introduces a 3D‐printed bistable mechanism integrated into tuned mass dampers (TMDs) for mechanically adaptive passive vibration suppression. Through optimized geometry, the bistable design provides adaptable vibration reduction across a broad range of scenarios, achieving effective vibration mitigation without complex controls or external ...

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

Advanced Engineering Materials, EarlyView.
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%.

Dynamic Precipitation during High‐Pressure Torsion of a Magnesium–Manganese Alloy

Advanced Engineering Materials, EarlyView.
An ultrafine‐grained alloy is produced by high‐pressure torsion of solutionized Mg–1.35 wt% Mn. Precipitation of nanometer‐scale Mn particles during deformation provides pinning sites. This prevents the formation of a bimodal grain structure and results in a finer grain size than for pure Mg.

Characterization of Defect Distribution in an Additively Manufactured AlSi10Mg as a Function of Processing Parameters and Correlations with Extreme Value Statistics

Advanced Engineering Materials, EarlyView.
Predicting extreme defects in additive manufacturing remains a key challenge limiting its structural reliability. This study proposes a statistical framework that integrates Extreme Value Theory with advanced process indicators to explore defect–process relationships and improve the estimation of critical defect sizes. The approach provides a basis for

COMPARATIVE STUDY ON THE CORROSION OF ALLOYS IN ARTIFICIAL SALIVA [PDF]

Romanian Journal of Stomatology, 2018
Four types of dental alloys used in metal-ceramic technology, two NiCr-based and two CoCr-based, were studied for corrosion resistance. Of the 4 types of alloys, circular samples of 14 mm in diameter and 4 mm thickness were poured into the dental ...

Effect of TiC/TiC–TiB2 on microstructure and mechanical properties of spray formed 7055 aluminum alloy TIG welded joints

Journal of Materials Research and Technology, 2021
Owing to the notorious hot-crack susceptibility and severe softening fusion-weld joints of Al–Zn–Mg–Cu alloys, they are generally considered unweldable. In this study, TiC/7xxx (TC) and TiC–TiB2/7xxx (BC) aluminum matrix composites, fabricated by in-situ
