ENERGETIC - PARTICLE SYNTHESIS OF NANOCOl " OS 1 TE - AI ALLOYS
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...
متن کاملSynthesis and mechanical properties of nanostructured Mg-Al-Nd alloys
In this work, nanostructured Mg-Al-Nd alloys were successfully fabricated using mechanical alloying method. Phase structures of the milled powders and the extruded rods were examined using X-ray diffraction (XRD) and the microstructures were observed using a transmission electron microscope (TEM). The element distributions were also examined by an energy dispersive spectroscopy (EDS) system. Th...
متن کاملPiezoelectric Ignition of Nanocomposite Energetic Materials Report
Piezoelectric initiators are a unique form of ignition for energetic material because the current and voltage are tied together by impact loading on the crystal. This study examines the ignition response of an energetic composite composed of aluminum (Al) and molybdenum trioxide (MoO3) nano-powders to the arc generated from a lead zirconate and lead titanate (PZT) piezocrystal. The mechanical s...
متن کاملSpaceborne Energetic Particle Instrumentation
The primary thrust of the APL space research program is to develop an understanding of the behavior and ultimate sources of the magnetic and electric fields, plasmas, and energetic particles that permeate the cosmos. We now know, for example, that the solar wind-a fully ionized hydrogen gas moving outward from the sun through the solar system at speeds of many hundreds of kilometers per second-...
متن کاملEXPERIMENTALl ANALYSIS OF PARTITION COEFFICIENT IN Al-Mg ALLOYS
Because the partition coefficient is one of the most important parameters affecting microsegregation, the aim of this research is to experimentally analyse the partition coefficient in Al-Mg alloys. In order to experimentally measure the partition coefficient, a series of quenching experiments during solidification were carried out. For this purpose binary Al-Mg alloys containing 6.7 and 10.2 w...
