FRACTURE CHARACTERISTICS OF ALUMINUM ALLOYS WETTED WITH LIQUID ZINC AMALGAM

Abstract

Fracture strength determinations were made on sheet specimens of aluminum alloys 1100, 2024, 5456, 6061, and 7075 in different conditions of temper after wetting with a liquid 2% zinc amalgam. Tests at ambient temperature disclosed that the wetted fracture strength of the alloys decreased with increasing time of wetted contact with the amalgam before stressing. This time dependence was most pronounced for alloys in the precipitation hardened condition in comparison to that for the same alloys in the annealed state or others in strain hardened tempers. Once wetting had been effected, there was a continued physical dissolution attack of the aluminum alloys by the amalgam. This attack, however, was not directly related to the noted time dependence of the wetted fracture strengths.
