Wave steadiness in aluminas
Plate impact experiments have been carried out on two aluminas of differing grain size using the Cambridge 50 mm gas gun. Tiles were constructed in thicknesses of 4, 8 and 12 mm and were impacted by 3 mm thick copper projectiles fired at 550 m S-'. The longitudinal stress in the tiles was recorded using manganin stress gauges and a 1 GS S-' storage oscilloscope. Measurements were made of the el...
متن کاملFormation of Zinc Aluminium Layered Double Hydroxides -4(2,4-dichlorophenoxy)butyrate Nanocompisites by Direct and Indirect Methods
4-(2,4-dichlorophenoxy)butyric acid (DPBA) was intercalated between the interlamellae of Zn/Al layered double hydroxides (LDHs). Two methods of intercalation were adopted, (a) direct synthesis by co-precipitation of metal nitrates and DPBA and (b) ion exchange of LDH nitrate with the organic anion. The resulting materials were characterized by x-ray diffraction and infrared spectroscopy. Both m...

متن کاملSurface Energies and Thermodynamic Phase Stability in Nanocrystalline Aluminas
Corundum, a-Al2O3, is the thermodynamically stable phase of coarsely crystalline aluminum oxide, but syntheses of nanocrystalline Al2O3 usually result in g-Al2O3. Adsorption microcalorimetry, thermogravimetric analyses, and Brunauer-Emmett-Teller adsorption experiments, coupled with recently reported high-temperature solution calorimetry data, prove that g-Al2O3 has a lower surface energy than ...
متن کاملCreep of Aluminium and Aluminium Alloys
This chapter constitutes an introduction to creep and to the creep response of Aluminium and its alloys. Its major goals are: to provide basic information on creep and its mechanisms to give a description of the more extensively used mathematical relations among creep variables (time, stress and temperature) to illustrate the creep response of pure Aluminium and of Al-Mg alloys to provide a syn...
