HEAT-CAPACITIES OF ALUMINUM-ALLOYS

In the framework of the European COST 507 project the specific heat ca pacities of aluminium alloys and metal matrix composites based thereon have been measured between 20 and 520 degrees C by differential scann ing calorimetry and stored in the databank THERSYST along with other t hermophysical properties mainly drawn from literature. The curves show the influence of additional elements and reinforcements, of the fabri cation process, thermomechanical treatment and scanning rate on the pr ecipitation and dissolution kinetics of the various metastable phases and their relative amounts. The database may be used to select existin g light alloys or elaborate new ones in view of specific technical app lications.
