surface structure/ compositionstructureenriched alloy layerfilmed Al alloysThe topmost 20 nm of an electropolished Al-1 at.% Cu alloy has been investigated at sub-nanometre resolution using medium-energy ion scattering. Differences in the composition and depth of the enriched Cu layer are observed....

12.7 wt% Si and 579 °C and the different microstructure formed due to a variation in alloy composition across the eutectic point is illustrated in Fig. 2(c). Al-Si based alloys used in AM are often multicomponent, such as the popular AlSi10Mg alloy. Thermodynamic software can ...
most commercially available high-strength Al alloys, like AA 7075, are not suitable for additive manufacturing due to their high susceptibility to solidification cracking. In this work, a custom Al alloy Al92Ti2Fe2Co2Ni2is fabricated by selective laser melting. Heterogeneous nanoscale medium...
This is an important aspect when developing Al-based alloys as H storage media and materials used in transportation and infrastructure for a coming H economy. Methods Materials The studied 7xxx Al alloy is with the composition of Al–6.22Zn–2.46Mg–2.13Cu–0.16Zr–0.02Fe in wt.% (Al–2.69...
A wide range of novel multicomponent amorphous alloys have been manufactured by melt-spinning, using an equiatomic substitution method for the early transition metal and late transition metal contents of Zr-based amorphous alloys. Amorphous alloys were formed over the composition range x=20–70 at.%...
Refined and metamorphic alloys are needed to add into pure aluminium-water, namely, it is needed to use after the completion of the refining and deslagging process to avoid the effect recession or weaken caused by impurities. METAL FLUXER SERIES Name Usage% Temperature/...
