The use of gamma rays in studying the homogeneity of the alloy (AL-Co-Ni) reinforced with chromium oxide

This research deals with the preparation number of composite materials by casting the base alloy (Al-Co-Ni) by adding chromium oxide (Cr2O3) as reinforcement material, by weight ratios of (5, 10, 15 wt%) for the base alloy, with heat treatment of the prepared alloys. The basic alloys and composite m...
