In this work, we investigated a novel Al-Mg-Si alloy, which was developed from an AA 6082, in order to considerably improve the yield and tensile strengths whilst retain excellent ductility. The new alloy possesses higher content of Si than specified by and, addition, it contains copper zirconium. characterized as-cast condition, after homogenization, extrusion, T6 heat treatment using light mi...

Ca2Si was successfully synthesized via a high-temperature melting furnace and spark plasma sintering process, allowing its thermoelectric properties to be studied. High-temperature furnaces were utilized inhibit the volatilization of Ca elements during preparation stage, ensuring production high-purity Ca2Si. The resistivity increased gradually with rising temperature reached 12 mΩ·cm at 873 K,...

Based on the 3 factors and levels orthogonal experiment method, compositional effects of Mg, Si, Ti addition microstructures, tensile properties, fracture behaviors high-pressure die-casting Al-xMg-ySi-zTi alloys have been investigated. The analysis variance shows that both Mg Si apparently influence properties alloys, while does not. mechanical are comprehensively influenced by amount eutectic...

Alüminyum ve alaşımları düşük yoğunluk, yüksek spesifik mukavemet, korozyon dayanımı, elektriksel ısıl iletkenlik özelliklerinden dolayı otomotiv, havacılık uzay, savunma sanayilerinde yaygın olarak kullanılmaktadırlar. Genellikle malzemelerin mukavemetlerinin artırılması bakımından, alüminyum alaşımlarında işlem deformasyon prosesleri uygulanmaktadır. Magnezyum bakır alaşım elementlerinin ilav...

The interplay between optical performance and the thermally activated interface chemistry of periodic Mg/SiC multilayers designed for application at 30.4 nm are investigated by optical (hard x-ray, soft x-ray and ultraviolet ranges, i.e. from 0.154 to 30.4 nm) reflectivity and x-ray emission spectroscopy. The multilayers are prepared by magnetron sputtering and then annealed up to a temperature...

In order to refine the microstructure and improve performance of direct energy deposited (DED) additively manufactured Al–Mg–Sc–Zr alloy, TiC-modified composites were prepared by DED effect TiC content on was studied. absence particle, alloy consisted fine grains with average size 8.36 μm, well-dispersed nano-Al3(Sc,Zr) particles inside Mg2Si phase along grain boundaries. With addition 1 wt% Ti...

The productivity and recovery of hot-rolled Al-Mg-Mn sheets often suffer from sodium-induced edge cracking. In this study, AA5182 ingots with different levels Na were prepared by direct-chill (DC) casting, then subsequently subjected to homogenisation hot-rolling processes. crack occurrence during hot rolling in the pass #11 (84% reduction) #18 (96% was investigated, special attention paid impa...
