Abstract
In order to investigate the influence of dispersed oxide particles on crack-formation in Al-Al2O3 alloys, series of tensile tests (20 to 550† C) and creep tests (450† C) were carried out on pure Al and on Al-0.7wt% Al2O3 specimens. Density measurements performed on broken samples showed no changes in pure Al but considerable decreases in the slightly oxidised Al. The observed influence of oxide is strong for the small percentage if compared with the behaviour of Al-Al2O3 alloys with much higher oxide contents.
