Abstract

Results are presented of the influence of thermal and thermo-mechanical processing on the tensile strength and stress corrosion resistance of Al-Mg alloys characterized by different combinations of the ancillary elements Cr, Mn and Zr. As a result of the processes described, the final wrought products exhibit higher yield strengths for a given stress corrosion resistance than conventional materials. This is attributed to the favorable distribution of dislocations and precipitates that is induced by the treatment. The combination of ancil lary elements is an important factor for optimizing the metallurgical properties of the alloys; evidence is given for the role played by the dispersoids containing Cr, Mn and Zr on both the grain structure and the distribution of β(Mp2Al3) particles.
