Sintered eutectoid P/M steel behaviour during cold upsetting

open access: yesMaterials Research, 2008
Cold upsetting experiments were carried out on sintered Fe-0.8%C steel preforms in order to evaluate the technical relationship that exist between the applied stresses against continuous deformation and densification.

Research on automatic spraying of single-walled carbon nanotubes and detection of spraying effects

open access: yesInternational Journal of Smart and Nano Materials, 2014
Single-walled carbon nanotubes (SWNTs) have been introduced as compliant electrodes for dielectric elastomers (DEs) due to fault tolerance. To acquire a better electrostrictive strain and longer lifetime, it is essential to obtain a certain and uniform ...

Adhesiveness of cold rolled steels for car body parts

open access: yesMaterials Research, 2007
The aim of this work was to evaluate the adhesiveness of uncoated and zinc-electrogalvanized steel sheets used in the automotive industry. Three types of adhesives, one acrylic and two epoxy resins, were employed to join low carbon cold rolled steels ...

High-spin state and magnetic coupling induced through interfacial orbital reconstruction observed in SrRuO3/LaNiO3 superlattice

open access: yesMaterials Research Letters, 2020
A high-spin state of SrRuO3 at the interface and large magnetic coupling were observed in SrRuO3/LaNiO3 superlattices. X-ray absorption spectroscopy and X-ray linear dichroism results show preferential occupation of the d3z2-r2 orbitals.

Predicting band offset of lattice matched ZnO and BeCdO heterojunction from first principles

open access: yesMaterials Research Letters, 2019
Using first-principles approach, we calculated the band gaps of wurtzite $ {\rm Be}_{1-x} $ Cd $ _x{\rm O} $ ternary alloy and the band offset of the lattice matched $ {\rm ZnO}/{\rm Be}_{0.44}{\rm Cd}_{0.56}{\rm O}[1\,1\,\overline {2}\,0 ...

The effect of adding boron in solidification microstructure of dilute iron-carbon alloy as assessed by phase-field modeling

open access: yesMaterials Research, 2011
Alloying element like boron, even in small addition, is well known to improve hardenability of steels. Its application can improve mechanical properties of steels and reduce alloying costs.
