چکیده
Abstract β-Ga 2 O 3 nanocrystals have been successfully obtained by the high-energy ball milling method. The nanocrystalline powders characterized using X-ray diffraction, transmission electron microscopy, energy-dispersive spectroscopy, and luminescent spectroscopy. diffraction patterns show a single gallium oxide structure formed in process with small amount of α-Ga phase. grains irregular shape were identified TEM technique. HRTEM images confirmed formation size distribution 50–80 nm. Three luminescence bands peaked at about 2.52, 2.91, 3.26 eV observed photoluminescence spectra. gradual blue shift emission maxima excitation fundamental absorption edge under different conditions was detected.

متن کاملThe Influence of Heat Treatment and High Energy Ball Milling on the Density, Hardness, and Wear Behavior of Al 7150 Alloy via Hot Uniaxial Compaction
The effect of the milling time & ageing on the hardness, density, and wear characteristics of Al 7150 alloy specimens made via powder metallurgy has been studied. The different constituents of Al 7150 alloy were processed in a planetary ball milling set up with a BPR of 10:1 for 5 hours, 10 hours, and 20 hours. At 400 °C, the milled powders were subsequently hot compacted in a punch die setup. ...
