An intercomparison of global oceanic precipitation climatologies [PDF]

open access: yes, 2007
Large-scale patterns of precipitation are important for the changes they may effect upon the circulation of the ocean. However, marine precipitation is very hard to quantify accurately.

TEM Study of High-Temperature Precipitation of Delta Phase in Inconel 718 Alloy [PDF]

open access: yes, 2011
Inconel 718 is widely used because of its ability to retain strength at up to 650◦C for long periods of time through coherent metastable γ” Ni3Nb precipitation associated with a smaller volume fraction of γ’ Ni3Al precipitates.

Effect of pre-aging on microstructure and mechanical properties of Al-Mg-Si alloy containing 0.1%In

open access: yesCailiao gongcheng, 2023
The combined effect of trace addition of In and different pre-aging processes on the microstructure and mechanical properties for Al-Mg-Si alloys was investigated by using hardness test, tensile test, scanning electron microscope (SEM) and transmission ...

Simultaneously enhanced strength and ductility in graphene nanosheet/Al-Cu-Mg nano-laminated composites by incorporating coarse domains

open access: yesMaterials Research Letters, 2023
A heterogeneous structure by designing soft/hard domains with dramatically different strengths is effective to maintain the high ductility of metals but it sacrifices the yield strength.

Primary and secondary precipitates in a hierarchical-precipitate-strengthened ferritic alloy [PDF]

open access: yesJournal of Alloys and Compounds, 2017
Abstract The microstructures of a hierarchical-precipitate-strengthened ferritic alloy are characterized, using transmission-electron microscopy (TEM) and atom-probe tomography (APT). The alloy shows duplex precipitates. The primary precipitate with an average edge length of 90 nm consists of NiAl- and Ni2TiAl-type phases, while the secondary ...

Interfacial gradient M7C3 carbides precipitation behavior and strengthening mechanisms of stainless steel/carbon steel clad plates [PDF]

open access: yes, 2022
The mechanical incompatibilities between ferrite and martensite at the cladding interface of stainless steel (SS)/carbon steel (CS) clad plates can result in stress concentration and interface cracks.

Effect of heat treatment on microstructure and mechanical property of selective laser melted high speed steel

open access: yesCailiao gongcheng, 2022
Based on selective laser melting (SLM), the high speed steel samples with nearly full density and low defects were prepared by using the printing strategy consisted of preheated printing substrate, low laser power and slow scanning speed.

Strengthening Mechanism of a Single Precipitate in a Metallic Nanocube

open access: yesNano Letters, 2018
Nanoprecipitates play a significant role in the strength, ductility, and damage tolerance of metallic alloys through their interaction with crystalline defects, especially dislocations. However, the difficulty of observing the action of individual precipitates during plastic deformation has made it challenging to conclusively determine the mechanisms ...
