Superplastic Deformation Behavior of 7B04 Al Alloy

open access: yes, 2017
The superplastic tensile tests were carried out for 7B04 Al alloy under a temperature range of 470-530℃ at a strain rate range of 0.0003-0.01s-1. Then,the superplastic deformation behavior and deformation mechanism of the material were investigated.

A Highly Ductile Composite of 3D‐Printed Poly(Lactic Acid) With InSe Particles and Flakes as a Filler

open access: yesSmartMat, Volume 6, Issue 1, February 2025.
The inherent brittleness of poly(lactic acid) (PLA) was addressed by incorporating indium selenide (InSe) particles and flakes as a reinforcing filler. The PLA/InSe composites are 1.5 times stronger and 5.5 times tougher than neat PLA materials. Compared with other fillers, InSe enables PLA to achieve better concurrent improvement in tension strength ...

Evolution of grain size distribution during deformation of superplastic materials [PDF]

open access: yes, 1997
Grain size distribution and its evolution during superplastic deformation has been studied for two materials- ultrahigh carbon steel, which has a two phase microstructure, and a copper alloy, which has a quasi-single phase microstructure.

Weakening Induced by Phase Nucleation in Metamorphic Rocks: Insights From Numerical Models

open access: yesGeochemistry, Geophysics, Geosystems, Volume 25, Issue 11, November 2024.
Abstract Metamorphic transformations involve important changes in material properties that can be responsible for rheological alterations of rocks. Studying the dynamics of these changes is therefore crucial to understand the weakening frequently observed in reactive rocks undergoing deformation. Here, we explore the effects of reaction dynamics on the

Thermoplastic bonding (TPB) of TiAl- and Ni-based alloys with Zr-Al-Ni-Cu bulk metallic glass

open access: yesMaterials & Design, 2019
The joining of dissimilar materials such as TiAl- and Ni-based alloys has always been a challenging work due to the larger differences in properties. In this work, a new strategy called thermoplastic bonding (TPB) was proposed and successfully applied in
