| Abstract: | Superplastic tensile tests of AINp/6061 Al Compostics, fabricated by powder metallurgy techniques, were performed st strain rates ranging from 10-1-10-3 s-1 and at temperatwes from 833 to 893 K. Hot rolling after extrusion was employed to obtain a fine grained structure before superplastic testing. The superplastic behavior of AINp/6061 Al Composites was compared with that of AIN particulate size. Differential scanning calorimeter was used to ascertain the possibility of any partial melting in the vicinity of optimum superplastic temperatures. |
