Analysis of β´(Cu4Ti) Precipitation During Isothermal Aging of a Cu-4wt.%Ti Alloy [PDF]

Materials Research, 2018
This work analyzed experimental and numerically the growth kinetics of β´precipitation of a Cu-4wt.%Ti alloy after aging at 400, 500 and 600 ºC for times from 0.0166 h to 200 h.

Partially Coherent Backscatter in Radar Observations of Precipitation [PDF]

Journal of the Atmospheric Sciences, 2010
Abstract Classical radar theory only considers incoherent backscatter from precipitation. Can precipitation generate coherent scatter as well? Until now, the accepted answer has been no, because hydrometeors are distributed sparsely in space (relative to radar wavelength) so that the continuum assumption used to explain coherent scatter ...

Achieving strength–ductility–corrosion resistance balance in Cu–Ni–Al alloy via heterogeneous grains and coherent nano-lamellar precipitation

Materials Research Letters
Achieving the strength–ductility–corrosion resistance balance in Cu–Ni–Al alloys is significant for marine engineering. Here, the Cu alloy featuring ‘heterogeneous grain distribution and coherent nano-lamellar precipitation’ was fabricated, which ...

Effect of La addition on Ag-rich phase formation and mechanical properties of Cu-2Ag alloys

Journal of Materials Research and Technology, 2022
A series of novel Cu-2Ag-xLa alloys with reinforced mechanical properties and enhanced electrical conductivities are developed. The effects of La addition on the microstructural features and mechanical properties of as-cast and solution treated Cu-2Ag ...

A coarsening model for coherent precipitates [PDF]

, 1991
The morphological evolution of coherent inclusions in elastic media is studied in two-dimensions. The inclusions are simple dilations with isotropic surface energy in a system with homogeneous elastic constants of negative anisotropy. The equilibrium sizes at which a circular inclusion transforms to a rectangle or square, and at which a square splits ...

Microstructure Dependence of Magnetic Properties for Al_1.5Fe₃Co₃Cr₁ Multi-Principal-Element Alloy

Metals
This study focuses on the microstructures and soft-magnetic properties of the Al1.5Fe3Co3Cr1 multi-principal-element alloy (MPEA) in different states. The MPEA was prepared using arc melting and suction-casting, followed by various heat treatments.

Mapping stress heterogeneity in single-crystal superalloys by novel submicron-resolved X-ray diffraction

Materials Research Letters
Coherent precipitation, a common strengthening approach, is typically subjected to spatial non-uniformity due to microscopic segregation, leading to multi-scale stress heterogeneity.

Circulating microRNA signatures of cachexia and cancer in Canis familiaris as a comparative oncology model for human disease

Molecular Oncology, EarlyView.
Circulating microRNAs as biomarkers of cachexia and sex‐specific cancer in senior dogs. In 25 client‐owned dogs, four circulating miRNAs (miR‐15a, miR‐15b, miR‐16, miR‐140) were downregulated in cachexia, with miR‐16 the strongest individual biomarker (AUC = 0.899).

Adenosine triphosphate as a modulator of protein interactions and stability

FEBS Open Bio, EarlyView.
ATP is best known as the cell's energy currency, but it also shapes how proteins fold, interact, aggregate and form biomolecular condensates. This review explains the emerging physical principles behind these effects, including weak binding to charged protein regions, magnesium‐dependent behaviour and concentration‐dependent control of protein ...
