Dispersion strengthened aluminum made by mechanical alloying

Alloy Phases and Structure


Dispersion strengthened aluminum with excellent combinations of electrical conductivity and tensile strength at room and elevated temperatures has been produced by mechanical alloying. The strength levels, obtained with only about 2.75 to 5.4 vol pct dispersoid (Al2O3 plus carbon), equal or surpass those of conventionally produced SAP containing 11.5 vol pct Al2O3. The electrical conductivity is considerably higher than that of SAP with comparable strength. It is concluded that these superior properties are due to a finer, more equiaxed dispersoid and a better dispersoid distribution than found in conventionally produced SAP.
