Effect of solution treatment on grain boundary structure of Inconel 617 alloy bar

open access: yesCailiao gongcheng
The grain-boundary microstructure of Inconel 617 alloy hot-rolled rods during cold drawing and subsequent solution treatment is investigated using the electron backscattering diffraction (EBSD) technique. The results reveal that the microstructure of the

Cold Drawing of Magnesium Alloy Tubes for Medical

open access: yes, 2011
Magnesium alloy is the lightest in practical metals, and it is used for housing small home appliance products and automobile parts. It is also expected to be a new material for stents, because of its possibility of systemic absorption. Fineness, thinness,

Comparison between Neutron Diffraction measurements and numerical simulation of residual stresses of a Wire-Drawing process

open access: yesMaterials Research, 2013
In this work, a drawing processed was simulated to calculate forces and the resulting residual stresses in the material. The calculated residual stresses were compared with experimentally measured residual stresses by the Neutron Diffraction Method.

A Dislocation Perspective on Strength and Toughness in Ceramics

open access: yesAdvanced Engineering Materials, EarlyView.
Dislocations in ceramics enjoy a long but yet under‐appreciated history. The three research waves for dislocations in ceramics highlight the topic evolution over the last 90 years. This review focuses on the impact of dislocation on strength and toughness in ceramics.

The effect of cold-drawing on the creep behavior of a nickel-4.2 percent aluminum alloy

open access: yes, 1966
Creep tests were made at 700, 900, and 1200 °F (644, 755, and 921 °K) on a nickel-4.2 percent aluminum alloy (Duranickel) initially as cold-drawn and as cold-drawn and age-hardened.

Exploring an Alternative to mRNA Vaccine Cold Chain Storage: MRNA‐Lipid Nanoparticle Stability When Dried in a Polymer Matrix

open access: yesAdvanced Functional Materials, EarlyView.
The nanostructure, size, and function of mRNA‐loaded lipid nanoparticles are evaluated before drying, within polymer microneedles, and after rehydration. The results reveal the polymer and LNP loadings required to recover nanostructure and preserve the delivery performance in dry‐state formulations.
