An investigation on micro-hardness, micro-structure and ductility of clad layer in copper clad aluminum wire under multi stage–NCWD

Materials Research Express, 2020
The copper clad aluminum (CCA) wire was fabricated by roll forming of copper foil around the aluminum wire rode. Non-continuous wire drawing (NCWD) was employed to study the effect of wire drawing parameters on ductility, micro-hardness and ...

Evaluation methods of elastoplastic response of components to earthquake motions (Consideration of elastoplastic behaviour on the response of single-degree-of-freedom systems)

Nihon Kikai Gakkai ronbunshu, 2016
A constant ductility response spectrum (CDRS) readily provides the yield strength of a single-degree-of-freedom (SDF) system necessary to limit the ductility imposed by a ground motion to a specified value.

The impact of the welded wire mesh as internal reinforcement on the flexural behavior of RC beams exposed to elevated temperature

Case Studies in Construction Materials, 2021
This paper investigates the efficiency of using the welded wire mesh (WWM) as internal reinforcement to regain the structural performance of heat-damaged reinforced concrete (RC) beams to achieve a 28-days average compressive cylinder strength of 40 MPa.

Overcoming the strength-ductility trade-off in additive manufactured AlSi10Mg plates by friction stir welding at a low rotational speed

Journal of Materials Research and Technology, 2023
The main problem in post-treatment of laser powder bed fusion (L-PBF) AlSi10Mg is the sharp reduction in strength when the ductility enhances, i.e. the problem of strength-ductility trade-off.

Electrochemical Evaluation of Compressed Selective Laser Melted AlSi7Mg and AlSi10Mg Alloys in Chloride Environment

Advanced Engineering Materials, EarlyView.
The corrosion performance of AlSi7Mg and AlSi10Mg alloys produced through selective laser melting (SLM) was examined under compressive stress in a chloride environment. Electrochemical analyses, including open‐circuit potential (OCP), potentiodynamic polarization (CPP), and electrochemical impedance spectroscopy (EIS), were complemented by scanning ...
