A new generation of alloys, which rely on a combination of various strengthening mechanisms, has been developed for application in molten salt nuclear reactors. In the current study, a battery of dispersion and precipitation-strengthened (DPS) NiMo-based alloys containing varying amounts of SiC (0.5-2.5 wt %) were prepared from Ni-Mo-SiC powder mixture via a mechanical alloying (MA) route follo...

In a previous study, we developed an abrasive-free polishing method named catalyst-referred etching (CARE) and used it for the planarization of silicon carbide (SiC) (0001). this method, Si atoms at step edges are preferentially removed through catalytically assisted hydrolysis reaction to obtain atomically smooth crystallographically well-ordered surface. However, removal rate is low (< nm/...

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. ...

The authors neglected to cite a related study that reports an ARPES experiment indicating the presence of multiple p bands in multilayer graphene on C-face SiC. 1 This is given below as Reference 1. In the present Article, nano-ARPES band mappings of individual graphene grains unambiguously show that multilayer C-face graphene exhibits multiple p-bands.

   Physical study of nano ribbon, tetragonal bundled and isolated nano tube SiC (7,0) are part of our project in knowing new nano material such a silicon carbide. These studies have been performed by density function theory. Effect of ribboning, tubulating and tetragonal bundling on the physical properties such as stability, structural constants, optical physics, chemical parameters and mag...

Investigation was to study the influence of pulse-impact on microstructure of Liquid-Phase-Pulse-Impact Diffusion Welding (LPPIDW) welded joints of aluminum matrix composite SiCp/A356, SiCp/6061Al, Al2O3p/6061Al. Results showed that under the effect of pulse-impact: 1) the interface state between reinforcement particle (SiC, Al2O3) and matrix was prominently; 2) the initial pernicious contact-s...
