Nanostructured Al/Ni energetic composites: processing, reaction properties and activation energy

open access: yesJournal of Materials Research and Technology, 2022
In this study, the nanostructured Al/Ni energetic composites were processed using the high-energy ball milling method. The milling conditions, i.e. the ball to powder ratio (BPR), ball sizes, and milling time, were varied to investigate their effect on ...

Nanoscale grains, high irreversibility field, and large critical current density as a function of high energy ball milling time in C-doped magnesium diboride

open access: yes, 2007
Magnesium diboride (MgB2) powder was mechanically alloyed by high energy ball milling with C to a composition of Mg(B0.95C0.05)2 and then sintered at 1000 C in a hot isostatic press. Milling times varied from 1 minute to 3000 minutes.

Effect of ball milling process on the photocatalytic performance of CdS/TiO2 composite

open access: yesNanotechnology Reviews, 2020
CdS/TiO2 composite photocatalysts were made by the method of secondary ball milling at different ball milling speeds, milling time, and material ratios. After the secondary ball milling process, parts of the samples were calcined at high temperatures.

Effect of the Addition of 4 wt% Zr to BCC Solid Solution Ti52V12Cr36 at Melting/Milling on Hydrogen Sorption Properties

open access: yesFrontiers in Materials, 2022
The addition of 4 wt% Zr to Ti52V12Cr36 alloy was carried out in two different ways: arc-melting or ball-milling. The cast alloy showed rapid hydrogen absorption up to 3.6 wt% of hydrogen capacity within 15 min.
