Influence of severe plastic deformation on the precipitation hardening of a FeSiTi steel [PDF]

, 2012
The combined strengthening effects of grain refinement and high precipitated volume fraction (~6at.%) on the mechanical properties of FeSiTi alloy subjected to SPD processing prior to aging treatment were investigated by atom probe tomography and ...

Thin‐Wall Single‐Crystal Gold Nanoelectrodes toward Advanced Chemical Probing and Imaging

Small, EarlyView.
We present a template‐assisted, non‐self‐limited polyol‐based growth strategy that realizes single‐crystalline, thin‐walled Au UMEs/NEs, as well as multifunctional probes, with high yield (>80%). The method provides precise control over electrode dimensions, from sub‐100 nm to micron‐scale radii and reliably produces long, continuous single‐crystal ...

Cryogenic Stress-Driven Grain Growth Observed via Microcompression with in situ Electron Backscatter Diffraction [PDF]

, 2020
The deformation of materials at cryogenic temperature is of interest for space, arctic, and fundamental science applications. In this work, a custom-built cooling system attached to a commercial picoindenter was used for in situ cryogenic ...

Effect of Double Annealing on the Microstructure and Mechanical Properties of a Medium Manganese Steel

steel research international, EarlyView.
A double intercritical annealing strategy is proposed to tailor the multiphase microstructure and mechanical response of a medium‐Mn steel. The treatment produces an ultrafine mixture of ferrite, martensite and multiple austenite populations with graded thermal and mechanical stability, formed through austenite reversion and controlled retransformation.

Woven Eutectic Lamellar Structures Lead to Ultrahigh Strength and Energy Absorption Capacity in Additively Manufactured Lattice Structures

Small Structures, Volume 6, Issue 5, May 2025.
Herein, AlCoCrFeNi2.1 is selected to produce lattice structures by selective laser melting. The as‐printed lattice structures consist of numerous colonies of nanosized eutectic lamellar structures which are bent and interwind with each other to form a woven microstructure. The unique microstructure leads to unprecedented effective metal strength, yield

Hydration mechanism of amorphous layer on the surface of ultrafine iron tailings particles in clinker-free cement system

Case Studies in Construction Materials
Due to the fact that the mineral composition in metal tailings is inert under normal conditions, and the fineness modulus of fine-grained tailings is much smaller than that of construction sand.

Nanostructured Cobalt Obtained by Combining Bottom-Up and Top-Down Approach

Metals, 2018
Nanostructured metallic materials can be obtained by two major processing strategies: a bottom-up approach that starts with powdered metals to be mechanically and chemically compacted via different compaction methodologies, and a top-down approach that ...

The mechanical properties of ultrafine-grained metals at elevated temperatures

, 2009
Ultrafine-grained materials, having grain sizes in the submicrometer or nanometer range, may be readily produced by processing bulk solids through the application of severe plastic deformation (SPD) and this leads to the possibility of revealing ...

First-place finish : imparting fine surface finishes when micromilling [PDF]

, 2010
There are several key milling practices that help impart fine surface finishes in micromilling. They include running at ultrahigh spindle speeds, carefully monitoring chip load, employing climb milling when possible and using CAM software to develop ...
