Abstract The newly prepared and stored highly active aluminum powder were mixed with common nitramine explosives HMX CL-20 at a mass ratio of 1:1, respectively. effects the two kinds high on thermal decomposition properties investigated by differential scanning calorimetry (DSC). explosion critical temperature mixture explosive was calculated. result shows that after joining aluminium powder, a...

Complex aluminium alloy components fabricated by powder metallurgy (P/M) offer the promise of a low cost and high strength-to-weight ratio, which meets the demands of the automotive sector. This paper describes the die compaction and sintering response of an atomised Al-6061 alloy powder containing Mg and Si produced by rapid solidification. A design of experiments is used involving three level...

Metal matrix composites (MMCs) have become attractive for engineering structural applications due to their excellent specific strength property and are increasingly seen as alternative to the conventional materials particularly in the automotive, aerospace and defence industries. Al/SiC MMC has aluminium matrix and the silicon carbide particles as reinforcements and exhibits many desirable mech...

Aluminium powder is of major interest in many applications but it presents a risk due to its high explosibility, particularly when dispersed in air. The safety is directly linked to the particles oxidation because the Minimum Ignition Energy (MIE), which is required to initiate an Al dust explosion, increases with the oxide layer thickness. This study provides a controlled method to furnish rep...

The application of cobalt and aluminium powders in unconstrained format, not as metal powder tubular wire nor pre-alloyed powder, is used this work to simplify weld alloying. objective study demonstrate the Submerged Arc Welding SAW alloy control oxygen content. Aluminium potential at pool-slag interface order prevent oxidation cobalt. results presented here show that with addition 70% yield Co...

<p>Various fingerprint powder preparations used for fingerprints have a color or contrast and sticky material good adhesion. However, some chemical substrates powders are toxic the potential to harm health. This research is essential overcome this problem using new natural , namely dragon fruit peel powder, as latent development that was simple, non-toxic, cheaper than commercial powder. ...

Abstract Magnesium, the lightest structural metal, has inherently poor corrosion resistance. In this study, we developed a magnesium-aluminium Mg-10.6Al-0.6Zn-0.3Mn alloy, additively manufactured by laser powder bed fusion. We reveal that alloy record low degradation rate amongst all magnesium alloys in practically relevant corrosive solutions, and it even withstands seawater corrosion. As test...
