Microstructural Changes in Aluminum Mechanically Milled Sintered by Conventional Method and Induction

Matrix Structure Evolution and Nanoreinforcement Distribution in Mechanically Milled and Spark Plasma Sintered Al-SiC Nanocomposites

Development of homogenous metal matrix nanocomposites with uniform distribution of nanoreinforcement, preserved matrix nanostructure features, and improved properties, was possible by means of innovative processing techniques. In this work, Al-SiC nanocomposites were synthesized by mechanical milling and consolidated through spark plasma sintering. Field Emission Scanning Electron Microscope (F...

Reduction of Surface hr~ >ion Caused by Helium Blistering in Sintered Beryllium and Sintered Aluminum Powder

Studies have been conducted to find Materials with microstructures which Minimize the formation of blisters. A promising class of materials appears to be sintered metal powder with small average grain sizes and low atomic number Z. Studies of the surface erosion of sintered aluminum powder (SAP 895) and of aluminum held at AOO'C due to blistering by 100 keV helium ions have been conducted and t...

Coexistence of Ferromagnetic and Glassy States in Mechanically Milled GdAl2

Measurements of DC susceptibility, AC susceptibility, and AC susceptibility with an applied DC bias field were performed on mechanically milled GdAl2. A paramagnetic phase exists above a temperature T ≈ 140 K. However, there are significant deviations from the Curie-Weiss Law in this temperature regime, suggesting multiple magnetic components. Fits to the high temperature data show that two Cur...

Mechanically Sintered Gallium#x02013;Indium Nanoparticles

DOI: 10.1002/adma.201404790 plowed pile of chips formed from a dried fi lm of EGaInNPs (see Experimental Section). Note the occurrence of microcracks in the deposits in Figure 1 , which is common in dried colloidal deposits. [ 21,22 ] Furthermore, the stability of the chips indicates “solid-like” behavior of the deposit and high interparticle adhesion, both characteristic of the oxide coating e...
