抄録

Influence of zirconium on structure and properties of aluminium alloys used at elevated working temperature are given in this paper. By following changes in micro-hardness as a function of time for different temperatures and at different zirconium contents, activation energy of the recovery process, which served as an indicator of the creep resistance of the alloys, was determined. A mathematical model which enables to evaluate and predict required quality of alloys was also defined.
