The elemental mixture of Mg-6 wt %Al-1 wt %Zn-0.3 wt %Mn (AZ61B) alloy powder and CaO particles was consolidated by an equal-channel angular bulk mechanical alloying (ECABMA) process to form a composite precursor. Subsequently, the precursor was subjected to a heat treatment to synthesize fine Al₂Ca particles via a solid-state reaction between the Mg-Al matrix and CaO additives. Scanning electr...

Ion implantation of 0 into Al and growth of Al(0) layers using electron-cyclotron resonance plasma and pulsed laser depositions produce composite alloys with a high density of nanometersize oxide precipitates in an Al matrix. The precipitates impart high strength to the alloy and reduced adhesion during sliding contact, while electrical conductivity and ductility are retained. Implantation of N...

Sandwich-structured composite zeolite membranes with enhanced hydrogen selectivity were prepared on porous α-Al(2)O(3) supports by using 3-aminopropyltriethoxysilane as an interlayer.

Correction for 'Externally controlled drug release using a gold nanorod contained composite membrane' by Kibeom Kim, et al., Nanoscale, 2016, 8, 11949-11955.

Creep can be dangerous for electromechanical, electronic and electrical connections, networks and devices. Recently, the metal matrix composites (MMC’s) are generally used for designing the electromechanical and electrical systems and devices due to their advantages. Therefore, analysis of the creep behavior is necessary and important for safe designing the fibrous composite devices. For achiev...

In-situ alumina-zirconia composite bodies were fabricated by heat treatment of gibbsite-zircon-kaolinite mixture at 1450℃. The current research investigated crystallization behavior and mechanical properties of the mentioned mixture in the presence of 5 wt.% MgO as an additive. X-ray diffraction (XRD) results showed that alumina, zirconia, and magnesium aluminosilicate were crystallized during ...

Abstract Although Cu–Al 2 O 3 composites have good comprehensive performance, higher mechanical properties and arc erosion resistance are still required to meet heavy-duty applications such as electromagnetic railguns. In this work, a novel hybrid SiC w /Cu–Al composite was successfully prepared by combining powder metallurgy internal oxidation. The microstructure behavior of the were studied. ...

In this research study, the effects of aluminum nitride (AlN) additive on the densification behavior and microstructure development of titanium diboride (TiB2) based ceramic matrix composite were investigated. In this way, a monolithic TiB2 ceramic and a TiB2–5 wt% AlN ultrahigh temperature ceramic composite were fabricated by spark plasma sintering (SPS) proces...
