Scanning microscopes will be vital elements in the atom engineer's toolbox, and our understanding of their operation continues to advance rapidly. We can look forward to finding a sound basis not only for imaging and spectroscopy of single atoms, but also their manipulation and the creation of wholly novel nanostructures. (residues 35–139) binds to SicP in an extended , non-globular conformatio...

In order to evaluate the uniform of SiCp reinforced aluminum metal-matrix composites (MMC) fabricated by powder metallurgy, the ultrasonic velocity imaging was carried out with the method of thickness independent reflector plate (TIRP). Ultrasonic velocity in MMC can be used to calculate the stiffness constants and Yang’s modulus, which are influenced by the volume percentage of SiCp. The TIRP ...

The initial discharge process of plasma electrolytic oxidation (PEO) on the 60 vol. % SiCP/2009 aluminum matrix composite in silicate solution was situ monitored by sound and vibration measurement techniques. underwater sound, airborne sample signals were detected 120 s PEO process, their generation mechanism discussed. In terms waveforms spectrograms signals, can be divided into five stages: c...

During heat treatment, the work piece experiences a range of heating rates depending upon the sizes and types of furnace. When the Al-Si-Mg cast alloy is heated to the solutionizing temperature , recrystallization takes place during the ramp-up stage. The effect of heating rate on recrystallization in the A356 (Al-Si-Mg) alloy was studied using dilatometric and calorimetric methods. Recrystalli...

Aluminum alloy A356 matrix syntactic foams filled with SiC hollow particles (SiCHP) are studied in the present work. Two compositions of syntactic foams are studied for quasi-static and high strain rate compression. In addition, dynamic mechanical analysis is conducted to study the temperature dependent energy dissipation and damping capabilities of these materials. The thermal characterization...

Al-Si-based casting alloys have a great potential in various industrial applications. Common strengthening strategies on these alloys are accompanied inevitably by sacrifice of ductility, known as strength-ductility trade-off dilemma. Here, we report a simple route by combining rapid solidification (RS) with a post-solidification heat treatment (PHT), i.e. a RS + PHT route, to break through thi...
