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 ...

Evaluating the Adequacy of Ductility Requirements of Seismic Design Codes [PDF]

Numerical Methods in Civil Engineering
Seismic design philosophy is based on this principal that destructive earthquakes have a low probability of occurrence, and it is not economical to design structures to perform elastically during such rare events.

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.

A super-ductile alloy for the die-casting of aluminium automotive body structural components [PDF]

, 2014
Super-ductile die-cast aluminium alloys are critical to future light-weighting of automotive body structures. This paper introduces a die-cast aluminium alloy that can satisfy the requirements of these applications.

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.

The effect of precipitation on strength and ductility in a Mg-Zn-Y alloy

, 2012
The effect of pre-ageing deformation on the size and distribution of beta-prime precipitates and subsequently on the resulting strength and ductility have been measured in a Mg-3.0at.%Zn-0.5at.%Y alloy.

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.
